Specific Heat Practice

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 degree Celsius.

Front

Which has a higher specific heat: water or wood?

Back

Water has a higher specific heat (4184 J/gºC) compared to wood (1760 J/gºC).

Front

Why is a low specific heat desirable for a cooking skillet?

Back

A low specific heat allows the skillet to change temperature quickly, making it more responsive for cooking.

Front

How does heat flow between objects?

Back

Heat flows from warm objects to cold objects.

Front

What happens to particles when heat is added to a substance?

Back

The particles speed up when heat is added.

Front

Calculate the heat required to raise the temperature of 1200 g of water from 23 °C to 39 °C if the specific heat of water is 4.18 J/gºC.

Back

80,256 J.

Front

What is the formula for calculating heat energy (Q)?

Back

Q = mass (m) × specific heat (c) × change in temperature (ΔT).

Front

If a substance has a high specific heat, what does that imply about its temperature change?

Back

It implies that the substance requires more energy to change its temperature.

Front

What is the specific heat of water in J/gºC?

Back

4.18 J/gºC.

Front

What is the specific heat of wood in J/gºC?

Back

1.76 J/gºC.
