Change Constant Heat Volume

In summary, enthalpy is a measure of total heat energy in a system and takes into account both internal energy and work done by or on the system. Supplying heat at constant volume means that the volume remains constant while heat is added, leading to an increase in enthalpy. The change in enthalpy can be calculated using the equation ΔH = Q.

The answer is 42.

1. What is enthalpy?

Enthalpy is a measure of the total heat energy in a system.

2. How is enthalpy different from internal energy?

Enthalpy takes into account not only the internal energy of a system, but also the work done by or on the system due to changes in pressure or volume.

3. What does it mean to supply heat at constant volume?

Supplying heat at constant volume means that the volume of the system remains constant during the process of adding heat.

4. What happens to enthalpy when heat is supplied at constant volume?

When heat is supplied at constant volume, the enthalpy of the system increases. This is because the heat energy is being added to the internal energy without any work being done.

5. How is enthalpy change calculated when heat is supplied at constant volume?

The enthalpy change when heat is supplied at constant volume can be calculated using the equation ΔH = Q, where ΔH is the change in enthalpy and Q is the heat added to the system.
