Answer 1

Answer:

5. Convection occurs when heat is transferred through a gas or liquid by the hotter material moving into a cooler area.

Example:boiling water - When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.

6. anything thing with molecules has motion. The molecules in cold things are moving slower more than the molecules of warm things.

7. The ice sculpture has more thermal energy because it has more molecules than the burning match, which equals more total kinetic energy.

For instance, if you lit up match underneath the ice sculpture, you will see that only a fraction of the ice has melted from the sculpture but by that time the match has burned out.

8.A thermal imaging, thermography or infrared camera is a camera that are sensitive to heat radiation.

9. The metal pan conducts the heat and through conduction, cooks the brownies.

10. The conduction also cooks the brownies in the glass pan, but since infrared goes right through the glass, they also cook by radiation.

11. you can measure something how hot is in Celsius or Fahrenheit. The temperature of something, is statement about how fast the molecules.

12. Freezers produce hardly any heat, but the more satisfying answer is that they are pumping lots of heat out of their chambers
