specific heat capacity and specific latent heat

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat energy required to raise the temperature of 1 kg of a substance by 1°C.

Front

What does a high specific heat capacity indicate about a substance?

Back

A high specific heat capacity indicates that the substance requires more energy to change its temperature.

Front

How is the specific heat capacity of a substance calculated?

Back

Specific heat capacity (c) is calculated using the formula: c = Q / (m * ΔT), where Q is the heat added, m is the mass, and ΔT is the change in temperature.

Front

What is specific latent heat?

Back

Specific latent heat is the amount of heat energy required to change the state of 1 kg of a substance without changing its temperature.

Front

What is the difference between specific heat capacity and specific latent heat?

Back

Specific heat capacity involves temperature change, while specific latent heat involves a change of state without a temperature change.

Front

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

Back

Q = m * c * ΔT for specific heat capacity, and Q = m * L for specific latent heat, where L is the specific latent heat.

Front

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

Back

During a phase change, the temperature of the substance remains constant while heat energy is absorbed or released.

Front

If 2 kg of water and 4 kg of water are heated to the same temperature, which requires more energy?

Back

The 4 kg of water requires twice the energy of the 2 kg of water to reach the same temperature.

Front

How do you calculate the increase in temperature when heating a substance?

Back

The increase in temperature can be calculated using the formula: ΔT = Q / (m * c), where Q is the heat energy supplied.

Front

What is the specific heat capacity of water?

Back

The specific heat capacity of water is approximately 4200 J kg^-1 °C^-1.
