Specific Heat

Front

What is specific heat?

Back

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

Front

What does a high specific heat indicate about a substance?

Back

A high specific heat means it requires more energy to change the temperature of the substance.

Front

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

Back

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

Front

What happens to heat flow when two objects at different temperatures come into contact?

Back

Heat flows from the warmer object to the cooler object until they reach thermal equilibrium (equal temperature).

Front

What is the symbol for thermal energy?

Back

The symbol for thermal energy is Q.

Front

If an object cools from 100°C to 50°C, what is the change in temperature?

Back

The change in temperature is 50°C.

Front

What is the relationship between specific heat and temperature change?

Back

A substance with a high specific heat will experience a smaller temperature change when it absorbs a given amount of heat compared to a substance with a low specific heat.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state reached when two objects in contact have the same temperature and no heat flows between them.

Front

How does specific heat affect climate?

Back

Water's high specific heat helps moderate climate by absorbing and releasing heat slowly, influencing weather patterns.

Front

What is the specific heat of water?

Back

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