HEAT: Specific Heat capacity

Front

What does the SI unit J/g°C measure?

Back

Specific heat.

Front

What is Specific Heat?

Back

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

Front

What is the specific heat (c) of copper?

Back

0.39 J/g°C.

Front

What is the formula to calculate temperature change (∆t) when heat (Q) is added?

Back

∆t = Q / (m * c) where m is mass and c is specific heat.

Front

What is the symbol for specific heat?

Back

c.

Front

What is the specific heat of water?

Back

4.18 J/g°C.

Front

What is the specific heat of wood?

Back

1.760 J/g°C.

Front

Which material requires more heat energy to raise its temperature: water or wood?

Back

Water.

Front

If 100 Joules of heat is added to 20 grams of copper, what is the temperature change (∆t)?

Back

12.82 °C.

Front

What is the relationship between specific heat and temperature change?

Back

Higher specific heat means more energy is required to change the temperature.
