Foam Will Be The Most Effective Insulating Material

In this science unit we had to keep 200 milliliters of boiling water hot as warm as possible for 20 minutes. For trial one we put tin foil all around flask so the heat waves would reflect back to the flask. Also we put tin foil on the top of the flask to stop convection because warm rises. So when the hot air rises we wanted the tin foil to reflect the hot air back into the flask. Then we were going to put the flask in in a wooden box with a small volume, but then keegan forgot to bring in the box so we had to put the flask with the tin foil around it in our ELA project.Then we put a ton of cotton balls all around the flask and tin foil to insulate the water in the flask. At the end of trial 1 we lost 15.7℃. One thing we did well is we kept the heat in by insulating with cotton balls. Another thing we did well was stopping convection by putting tin foil on the top.

The group first noticed that from 0-2 minutes and from 2-4 minutes, the water’s temperature decreased a lot. After four minutes, the temperature started to decrease at a steady pace. Within the first four minutes, the water temperature decreased from 100℉ to 80℉. Also, the group notice that the temperature of the boiling water with saran wrap decreased faster and dropped more than all of the other groups. This shows that saran wrap is not a good insulator because the temperature dropped so much in a short period of

In an article called “Heat Transfer by conduction” by Mike Brown, it states “Thermal energy in the vibrating particles or molecules is passed on to nearby particles in a process called conduction”. This explains to us the process of conduction in which it relates to our design because when we insert the thermometer into the warm water, our goal is to keep the water warm with our cup so that once the thermometer makes DIRECT contact with the warm water, it will heat up the thermometer and give us an exact temperature.

Aerogel is another certified product in Cradle to Cradle. It is an advanced insulation with the highest R-value that exists in the market, between R8 and R11. It is made of 95% air and gels that prevent heat flow through the material. It is lightweight and available as blankets which makes them easy to install. However, these products are one of the most expensive insulating materials in the

People choose to install insulation in their homes for various reasons. With there being several options as to what type of insulation homeowners can have installed, many base their decision off of the benefits they are expecting to reap from installing insulation. Should you be considering installing insulation in your home, you may find energy efficient foam insulation to be a good choice for multiple reasons.

In this experiment the specific heats of aluminum and copper were found. Through calculations and the experiments, the purpose of this lab, which was to determine the specific heat of two metal was achieved. According to the data, the specific heat of aluminum is 0.495 J/g℃ and copper’s is 0.168J/g℃. However, sources of error during this lab did occur, including assumptions made and the calorimeter system used. It was assumed that the metal reached the same temperature as the boiling water, however this was not calculated. Due to this the metal may not have reached the same temperature was the water in the beaker thus skewing the results of the specific heat. In addition, the assumption that the temperature of the metal and water became equal

Technology: Regulator® Insulation. “Regulator Insulation provides phenomenal compressibility, light weight warmth and moisture transport, whether used alone or as part of a layering system.” (Patagonia)

The multi layer shielding will also help insulate thes space station because according to NASA.gov, the outside of the International Space Station ranges from temperatures of 250 deg. F. to -250 deg. F. The multi layer insulation is made of three materials that each play an important role. There is also certain order each layer has to be placed. NASA also uses some of this insulation. The first material, being the farthest from the actual space settlement, is Kapton. Kapton is a great insulation for cold temperatures. It is also a Polyimide film which are known for their high heat resistance. Kapton comes before aluminized Mylar. Kapton is really heavy and it protects the fragile aluminized Mylar. Aluminized Mylar helps with radiation protection and heat protective. The last material is Dacron. Dacron has hydrogen content that absorbs radiation. You then would keep repeating the order and Dacron goes at the end to prevent conduction between layers. The order would be Kapton, Aluminized Mylar, Dacron, Kapton, Aluminized Mylar, Dacron over and over again. This is the way BEARTH™ will protect itself from radiation and will also protect us from more heat coming in. This does not stop the heat inside from leaving, every thing that creates heat in BEARTH™ will be turned into heat. BEARTH™ has ways to remove this heat as

Perhaps one of the major advances in insulating our homes in the last 30 years was the increased use of polyurethane foams for filling the cavities between walls. Whilst this made our homes much more energy efficient it was actually a technology that was first invented back in the 1940s in the United States.

I am aware that you need to decide what type of insulation is best for your basement in your new home. Insulation, in homes, are very important and sometimes overlooked. It is energy efficient and it keeps your house cool in the summer and warm in the winter. Insulation is the reason why we feel comfortable in our own homes. Here is a brief explanation of how: because heat travels, it flows out in the winter and in the summer, heat flows in. When your house is insulated it reduces the heat flow and saves you money.

In conclusion, the experiments showed that my hypothesis for salinity is not supported because hot water is less dense than cold water, therefore, the hot water floated on the cold water. Hot air floats and cold air sinks which creates wind so the same reasoning could be used for hot water floats and cold water sinks. The research talked about how ice is less dense than water but never directly stated that cold water was less than water also. An assumption that the same thing applied to cold water was made when creating the hypothesis. On the other hand, the results supported the hypothesis for temperature, showing how salt water would remain on the bottom or move there and fresh water would stay on the top or move there as well. Research

In part A of the experiment we added 100 degree Celsius water to room temperature and tracked the temperature of the mixture to see how much it changed. Using this information we were able to calculate how much energy was given off by the how water and how much energy was absorbed by the cold water. The difference of the absolute values of these two values divided by the difference in temperature gave us the calorimeter constant. The calorimeter constant is an important value because it allow us to calculate how much energy is absorbed by the calorimeter in other reactions. Our calorimeter constant makes sense because it is a smaller value and with the colorimeter being Styrofoam, and insulator, the amount of heat absorbed by the calorimeter

We decided to use cotton batting as our insulation. We used cotton batting because with insulation it slows the transfer of thermal energy, either coming in or going out of the house. In today’s houses, those with no insulation can lose up to 60 percent of their energy. This happens because the fiberglass, mineral wool, plastic fibers, and natural fibers found within today’s houses are packed so that when the heat tries to transfer it slows down because it has to go through those minerals first.

The foam consist of a mixture of water, forming agent, and air . As water flows, the foaming agent is mixed and the extinguishing agent is created. With every deluge systems specific purpose and design, it will require foam to have different foam densities. Foam extinguishment consists of cooling the fire and displacing of oxygen. It also suppresses vapors that can be flammable when mixed with air. You will find foam being generally used on class A and B fires. Special designed nozzles need to be in place for foam usage. One type commonly used are foam guns. Foam guns aim to cool fire from a distance. There is also a nozzle that can alternate between foam and water called foam/water jet pipe. You will find these foam nozzle systems in oil refineries, laboratories, and any places with hazardous materials. The use of foam can be of great service due to its ability to flow over practically any surface, can be manipulated to extinguish many different types of hazardous fires. The only downside will be the cost and clean up time required, which tends to be more than other extinguishing

Building a new house is an exciting endeavor. If you are lucky, you get to customize aspects of your home to personalize your home. A custom-built home gives you a great opportunity to ensure your home is efficient starting with your walls. Before the builder encloses your walls, you should choose insulation that will help you conserve energy.
