Q

Front

Which material requires more energy to raise its temperature by 1ºC: Water (4.184 J/gºC) or Wood (1.760 J/gºC)?

Back

Water requires more energy.

Front

What is the equation to measure change in thermal energy?

Back

Q = mCₚΔt

Front

Which object heats up faster: Object A (4.45 J/gºC) or Object B (1.82 J/gºC)?

Back

Object B heats up faster because it has a lower specific heat.

Front

Define specific heat.

Back

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

Front

What does a higher specific heat indicate about a substance?

Back

A higher specific heat indicates that the substance can absorb more heat without a significant change in temperature.

Front

What is the specific heat of water?

Back

4.184 J/gºC

Front

What is the specific heat of wood?

Back

1.760 J/gºC

Front

If 100 J of heat is added to 50 g of a substance with a specific heat of 2 J/gºC, what will be the change in temperature?

Back

Δt = Q/(mCₚ) = 100 J / (50 g * 2 J/gºC) = 1ºC.
