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

What is the specific heat of aluminum?

Back

0.21 cal/g°C.

Front

How do you calculate the heat (Q) released or absorbed?

Back

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

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of molecules.

Front

What happens to the temperature of a substance with a high specific heat when energy is added?

Back

It requires more energy to change its temperature.

Front

If 4000 joules of energy is added to 100 mL of water and 1000 mL of water, which will have a bigger change in temperature?

Back

100 mL of water will have a bigger change in temperature.

Front

What is the formula for calculating change in thermal energy?

Back

Q = mc∆t.

Front

What does a high specific heat indicate about a substance?

Back

It indicates that the substance can absorb a lot of heat without a significant change in temperature.

Front

What is the relationship between mass and temperature change when heat is added?

Back

For the same amount of heat added, a smaller mass will experience a larger temperature change.

Front

What is the unit of specific heat?

Back

The unit of specific heat is typically expressed in cal/g°C or J/g°C.
