Temperature Vs. Heat Flashcards
0
Q
Temperature of a substance
A
Is a measure of it’s thermal energy. The hotter an object, the greater the random motion of the atoms and molecules that compose it, and higher the temperature.
1
Q
Thermal energy
A
The atoms and molecules that compose matter are in constant random motion
2
Q
Heat
A
Heat, which has units of energy, is the transfer or exchange of thermal energy caused by a temperature difference. Temperature, by contrast, is a measure of the thermal energy of matter (not the exchange of thermal energy)
3
Q
Example of heat (transfer or exchange of energy)
A
When an ice cube is dropped into a warm cup of water, energy is transferred from the water to the ice, resulting in the cooling of the water
