7e: Specific Heat

Front

What is specific heat?

Back

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

Front

Why do particles slow down when a substance cools?

Back

As a substance cools, its particles lose energy, causing them to move slower.

Front

Which material has the highest specific heat: Water, Sand, or Metal?

Back

Water has the highest specific heat among these materials.

Front

What does it mean if a material has a low specific heat?

Back

A material with a low specific heat heats up quickly when energy is added and cools down quickly when energy is removed.

Front

How does the specific heat of water affect climate?

Back

Water's high specific heat helps moderate temperatures in coastal areas, preventing extreme temperature changes.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, related to its temperature.

Front

If two substances are at the same temperature, which has more thermal energy: a large mass or a small mass?

Back

The large mass has more thermal energy because it contains more particles.

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

Why does sand heat up faster than water?

Back

Sand has a lower specific heat than water, allowing it to heat up more quickly.

Front

What is the relationship between specific heat and temperature change?

Back

The greater the specific heat, the smaller the temperature change for a given amount of heat added.
