The Temperature Changing And The Water Melting

After 5 min passed the plastic container created a thin layer of ice surrounding the container.

1. For this experiment, what were the independent variable and the dependent variable? What were the constants?

Experiment: See lab sheet. In this experiment there was no control. The independent variables in this experiment are the time, and the amount of sand and water put into the cans. The dependent variable is the degrees (in Celsius) that

The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of the paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.

ziplock bag and closed it with as little air in it as possible left in it. The other gummy bear

Cotton is a good heat insulator. In our thermal insulating test, we put three hundred milliliters of room temperature water into a pan. Then we placed four containers into the pan, three containers had different fiber samples and one was empty. The empty container was a control to compare back to. After recording the original temperatures, we added the ice cubes. We took the temperature of the cotton container and continued to do so every minute for ten minutes. The

Then we put the flask in the middle of the box on top of a ton of cotton balls and a layer of tin foil to stop conduction, then we put pieces of tin foil wrapped cardboard around the flask in the box. After that we stuffed about 200 cotton balls in the walls of the box in between the cardboard and the outside of the box to insulate the walls. Also when we put the flask in the box we taped it shut with black duct tape to stop convection because shiny stuff reflects. After we tested our trial 2 project we found out that we lost 13.7℃. ONe thing we did well on trial to was that we insulated the walls very with cotton balls. Also we stopped conduction pretty well because the flask was not touching anything ,but the tin

Also, before you put in the blanket or loose insulation, be sure to seal all the cracks, vents, and pipes with spray foam insulation from a can. Check for air leaks around windows and other openings and seal any you find with caulk or the spray foam.

Avoid touching the bottom of the bowl or pot, wait for it to cool down.

Cover with a cling wrap and chill for an hour or overnight to allow the mixture to firm up.

Insulated Storage Compartments – When you are on the go, you want to be able to store milk for later. All you need to do is keep an ice pack in the storage compartment and you are ready for what the day may bring.

The water bottles insulation was effective, because when comparing the average change in temperature from the beginning to the end for the insulated bottle (which is 2.7’C) and the non-insulated control bottle (which is 3.9’C), there is a 1.2’C difference in temperature change. To improve my current design, I could model it more after the design of a thermos, a flask that effectively keeps liquids hot or cold. I could add a layer of silver on the inside to prevent heat from coming in and escaping the bottle by radiation, or a thin layer of glass on the outside to prevent heat from entering or leaving the bottle by conduction. A more simple improvement could simply be to add more tinfoil, to prevent less heat from escaping and create more of

My goal of this project was to build a structure to keep my ice cube from melting. To build the house I got a coffee cup turned upside down and put tin foil all around it. I put a ice pack in the coffee cup and placed the ice pack in a ziplock bag and put it in the coffee cup. and then I put popsicle sticks on top. Some of my limitations were time, and it was hard to get the heat transfer because everyone was using them. My creation did pretty good. The tin foil reflected the light, and the coffee cup protected the ice

Make sure you have the correct equipment for the job, such as fridges, freezers, chill well, an oven, microwave, hold holding counter and a probe thermometer. We check that our probe is working correctly on a weekly basis by doing a calibration test. We place the probe it
