Heat, Temperature & Thermal Energy

Front

What is the definition of heat?

Back

Heat is the energy transferred between two objects due to a temperature difference.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is the formula for calculating heat energy?

Back

Q = mc∆t, where Q is heat energy, m is mass, c is specific heat, and ∆t is the change in temperature.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

How does thermal energy move?

Back

Thermal energy always moves from hot to cold.

Front

What is the specific heat of water?

Back

The specific heat of water is approximately 4.18 J/g°C.
