Chapter Eleven, Lesson One: Temperature, Thermal Energy, and Heat Flashcards
1
Q
temperature
A
Temperature is a measure of how hot or cold something is compared to a reference point. Temperature is a measure of the average kinetic energy of the particles in an object.
2
Q
Fahrenheit scale
A
The United States uses the Fahrenheit scale to measure temperature.
3
Q
Celsius scale
A
Most countries use the Celsius scale to measure temperature.
4
Q
Kelvin scale
A
Many scientists use the Kelvin scale. A temperature change of 1 K is the same temperature change as 1°C.
5
Q
absolute zero
A
Zero kelvins, or absolute zero, is the lowest temperature possible. At absolute zero, particles have no kinetic energy. Zero K is equal to -273°C.
6
Q
heat
A
Heat is the transfer of thermal energy from a warmer object to a cooler object.
