What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius (or 1 Kelvin).

Front

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

Back

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

What happens to heat energy when a substance changes from solid to liquid?

Back

Heat energy is absorbed during the phase change, known as latent heat of fusion.

What is the latent heat of fusion for water?

Back

The latent heat of fusion for water is approximately 334 J/g.

Front

What is the boiling point of water at 1 atm pressure?

Back

The boiling point of water at 1 atm pressure is 100°C.

Front

How do you calculate the heat absorbed by water when it is heated?

Back

Use the formula q = m * c * ΔT, where m is the mass of water, c is the specific heat capacity of water (4.18 J/g·K), and ΔT is the change in temperature.

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is 4.18 J/g·K.

Front

What occurs when two substances at different temperatures are placed in contact?

Back

Heat will flow from the hotter substance to the cooler substance until thermal equilibrium is reached.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact no longer transfer heat to each other, meaning they are at the same temperature.

Front

How do you determine the final temperature when two substances are mixed?

Back

Use the principle of conservation of energy: heat lost by the hot substance = heat gained by the cold substance.
