U4 Zone 1: Transfer of Heat

Front

What is the term for the amount of energy required to raise the temperature of 1 kg of a substance by 1ºC?

Back

Specific Heat

Front

Why is sand at the beach typically hotter than the water?

Back

Sand has a lower specific heat than water.

Front

What does a high specific heat indicate about a substance's temperature change?

Back

It requires more energy to change temperature.

Front

Define specific heat capacity.

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is the specific heat of water compared to most other substances?

Back

Water has a high specific heat compared to most other substances.

Front

How does specific heat affect climate and weather patterns?

Back

Areas with large bodies of water tend to have milder climates due to water's high specific heat.

Front

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

Back

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

Front

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

Back

The temperature of the substance increases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two bodies in contact do not exchange heat, meaning they are at the same temperature.

Front

How does the specific heat of a substance influence its use in cooking?

Back

Substances with lower specific heat heat up quickly, making them suitable for quick cooking, while those with higher specific heat retain heat longer.
