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 needs more heat energy to raise the temperature, water or wood?

Back

Water

Front

What does a higher specific heat indicate about a material?

Back

It requires more energy to change its temperature.

Front

What is the formula for calculating thermal energy?

Back

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

Front

If a material has a specific heat of 2 J/g°C, how much energy is needed to raise the temperature of 100g by 5°C?

Back

1000 J (Q = mcΔT = 100g * 2 J/g°C * 5°C)
