Front

What unit do you use to measure Thermal Energy?

Back

J

Front

What is specific heat?

Back

The amount of thermal energy required to increase the temperature of 1kg of a material by 1° Celsius.

Front

A material was cooled from 100ºC to 40ºC. What is the temperature change?

Back

-60ºC

Front

A measure of the average kinetic energy of the individual particles in an object is called:

Back

temperature

Front

The movement of thermal energy from a warmer object to a cooler object is called:

Back

heat

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is heat, m is mass, c is specific heat, and ΔT is the change in temperature.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact with each other reach the same temperature.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

The transfer of thermal energy through electromagnetic waves.
