Heat

   

Define: Heat is

  1. A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.

Heat is a sum quantity amount measured in calories.

   

A calorie is the amount of energy required to change 1 cm3 of water (H2O) by 1°C.

   

Heat moves by conduction, convection, and radiation from high temperature areas (or objects) to low temperature areas (or objects).

   

Would a large container or a small container of water heat up faster?

Temperature

   

Define: Temperature is

   

Pasted from <http://www.answers.com/Temperature?cat=health>

   

Temperature is a average quality of the motion energy of all particles in a sample, measured in °C (Celsius), °F (Fahrenheit), or K (Kelvin).

   

Temperatures that you should know:

   

Boiling Point of Water (H2O)

100°C

212°F

373 K

Freezing / Melting Point of Water (H2O)

0°C

32°F

273 K

Absolute Zero

-273°C

-460°F

0 K
