Specific Heat Capacity Review Unit 3.5

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat energy required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

How do you calculate the energy lost or gained using specific heat capacity?

Back

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

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is approximately 4.18 J/g°C.

Front

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

Back

A high specific heat capacity means the substance will experience a smaller temperature change when it absorbs or loses heat.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases as it absorbs heat.

Front

What is the change in temperature if a substance cools from 80°C to 30°C?

Back

The change in temperature is 50°C.

Front

Which material has a lower specific heat capacity: sand or water?

Back

Sand has a lower specific heat capacity than water.

Front

Why does water take longer to heat up compared to metals?

Back

Water has a higher specific heat capacity than metals, meaning it requires more energy to increase its temperature.

Front

What is the specific heat capacity of graphite?

Back

The specific heat capacity of graphite is 0.709 J/g°C.

Front

If 100 mL of water and 1000 mL of water are heated, which will heat up faster?

Back

100 mL of water will heat up faster than 1000 mL.
