Thermal Insulator Space

1)My Hypotheses Is That The Cup With Foal Rapped Around it is the one that will take more time to cool down than the one with foal.

2)My Observation is that when i watched the water covered in foal and the one not covered in foal i saw that the one in foul is keeping the heat inside so it wont get any colder in the inside of the insulator.
The One without foal the tempature went down quick beacause the heat was not coming in and had no insulator.

3)Also I Believe, Tin Foal Is A Great Insulator To Keep The Heat Inside the object. Because If You Made Tortillas And Put Tin Foal Over It Heat Keeps The Heat Inside To Keep It Warm And Not Nasty.

Task 5

Colors don't absorb "heat". Colors absorb light. Which color is most effective at being heated by light it absorbs.


A violet color will absorb a photon of violet light, and re-emit some of it.Our Sun's light does not carry too many violet photons, so we always call these surfaces "cool".


So you can guess "Red", and know that it is the light source, and not the color, that makes it hotter.

The Project We Picked Was About How Does Colors Absorb Heat.

Task 4

Task4
Cooking, ultimately, is about heat, how heat enters the food and what happens to the food when it enters. This article focuses on heat transfer in cooking, or how heat is applied to and enters food. I won't spend much time on the chemical reactions that occur in food during cooking.

Heat Energy

Conduction-a spoon in a cup of hot soup becomes warmer because the heat from the soup makes the spoon hotter.They only feel colder because they conduct heat away from your hand.

Convection-is the transfer of heat by the actual movement of the warmed matter Convection is the transfer of heat energy in a gas or liquid by movement of currents.


Radiation:. Sunlight is a form of radiation that is radiated through space to our planet without the aid of fluids or solids.
