Finding The Most Effective Insulator Out Of The Metal, Polymer, And Cotton

Insulation slows the process of heat leaving an object. Most insulation contains lots of air spaces. The air spaces slow the flow of heat leaving the object because the heat takes longer to travel through the air spaces. Insulation is a material or substance that is used to stop heat, electricity, or sound from going into or out of something (Insulation, 2015, pg. 1). Insulation is commonly thought of in

Heat: The amount of energy associated with the movement of atoms and molecules in matter.

In my project, I will do an experiment to find out which material makes ice melt the fastest while the temperature of the room will remain the same. This research is important because if you are short on ice and you need it you can figure out which material will make your ice last the longest if you have no insulation. For example, if you were in the desert and had a cooler you would know what to put in your cooler to make your ice last the longest. I will be testing with three different materials: steel, wood, and fabric. My hypothesis is if the steel retains the ice's cold temperature then it will take the longest for the ice to melt. My goal is to help cooler companies improve their coolers by outlining them with whatever material helps

Insulator – Do not allow electric charges to pass through them. Electrons in the atoms and molecules move very slightly to one side of the object but are not released.

3. Test the effect of a magnet on each substance by passing the magnet under

2. Conduction heat loss by direct molecule to molecule transfer from one surface to another. (skin loses heat through direct contact with cooler air, water, or other surfaces)

2. Bring the Styrofoam cup close to another person's hair. What do you observe? What conclusions can you make regarding charged Styrofoam?

Heat is a form of energy, sometimes called thermal energy, which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact, they will, given sufficient time, both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured in a device called a calorimeter, an insulating container that minimizes heat exchange between its contents and the surrounding. Heat flow in a device called a calorimeter. In this experiment, we should find the heat capacity of the

There are 3 types of metals for electricity conducting: metallic conductor, semiconductor, and superconductor. Metallic conductors allow the free flow of ions and electrons through a sample; and its conductivity decreases as the temperature increases.

They started to look at many different materials but couldn’t find anything. They thought maybe they could find a material that works like an ice pack, to keep it cold on the inside. They did a bunch of research and finally found a material that might work, Alumina silica hydrate fibers.

Then, measure the absorbance at the time that was decided as the optimal in step four.

Heat is a form of energy that is transferred between two substances at different temperatures. The flow of the energy is from the object of higher temperature to the object of lower temperature. The heat is measured in units of energy, usually calories or joules. Temperature on the other hand, is how cold or hot an object is. The temperature is the average kinetic energy per molecule of a substance. This is measured in degrees on the Celsius or Fahrenheit or in Kelvins.

12. The crocodile clips are attached to the copper electrodes of the experimental apparatus and the power supply is turned on. Simultaneously, the stopclock is started. The thermometer is checked every 30s. 13. After 300s the stopclock is stopped and the power supply is turned off. The negative cathode is carefully removed and is dried using a hair dryer. 14. When dry the negative cathode is placed on the electronic milligram balance and its final mass is recorded. 15. The positive anode and negative anode of the experimental apparatus are disposed and the electrolyte is poured out to ensure that the anode slime (impurities) does not contaminate the solution. 16. The electrodes of the experimental apparatus are replaced with new copper strips. 17. Steps 7 to 16 are repeated. However, this time, the rheostat is adjusted using the calibration apparatus until the multimeter shows approximate readings of 0.40 A, 0.60 A, 0.80 A and 1.00 A respectively. 18. Time permitting, the entire experiment is repeated. Safety Copper sulphate may cause irritation and burns if it comes into contact with the eyes. As standard lab procedure, safety goggles and lab coats must be worn at all times. Control of Variables Volume of Electrolyte Used

Overall, the experiment succeeded that the metals show the theoretical properties. Differences existed in the mathematical calculation of the actual length. These differences, however, it can be accounted for by experimental error; more over there are uncertainty on purity of the

Now we will move onto other materials that are involved with electronics. The next group of materials that will be discussed are insulators. An insulator is a material that does not conduct electricity at all but will resist or stop it from traveling further. An insulating atom has eight electrons in its valance shell which makes this shell complete. Eight is the most electrons that any atoms can have in their valance shell this is why these are called insulators, no more electrons can fit in the valance shell of these atoms.
