Specific Heat Capacity Flashcard

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

Why is specific heat capacity important in cooking?

Back

Specific heat capacity helps determine how quickly a substance heats up or cools down, which is crucial for cooking food evenly.

Front

What is the specific heat capacity of water?

Back

4.18 J/g°C.

Front

What does a heating curve represent?

Back

A heating curve shows how the temperature of a substance changes as it absorbs heat over time, indicating phase changes.

Front

What is the boiling point of water at standard atmospheric pressure?

Back

100°C.

Front

What is the freezing point of water?

Back

0°C.

Front

What line segment on a phase diagram represents the solid state?

Back

A-B represents the solid state.

Front

How does specific heat capacity affect climate?

Back

Water's high specific heat capacity helps regulate temperatures in coastal areas, preventing extreme temperature fluctuations.

Front

What happens to the temperature of a substance during a phase change?

Back

The temperature remains constant during a phase change, even though heat is being added or removed.

Front

What is the relationship between specific heat capacity and temperature change?

Back

The greater the specific heat capacity, the less the temperature of the substance will change when it absorbs a given amount of heat.
