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°C.

Front

What does a low specific heat indicate about a substance?

Back

A low specific heat indicates that the substance heats up quickly with added energy.

Front

What is the specific heat of water?

Back

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

Front

If 200 J of heat is added to 50 g of a substance with a specific heat of 0.5 J/g°C, what is the change in temperature?

Back

The change in temperature is 8°C.

Front

What is the relationship between heat and temperature?

Back

Heat is the energy transferred due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.
