Enthalpy

The enthalpy of combustion is the amount of heat released when a substance is burned in oxygen.

The enthalpy of vaporization is the amount of heat energy required to convert a liquid substance into a gas.

The enthalpy of a substance is affected by changes in temperature and pressure.

The enthalpy of solution is the heat absorbed or released when a substance dissolves in a solvent.

The enthalpy of a system can be calculated by adding the internal energy of the system to the product of pressure and volume.

The enthalpy of a mixture of gases depends on the partial pressures and mole fractions of the gases.

Enthalpy is a state function, which means it depends only on the initial and final states of a system.

The enthalpy of a gas is related to its internal energy and pressure.

The enthalpy change during the combustion of propane in a grill produces the heat used for cooking food.

Enthalpy is often used to describe the energy changes that occur in chemical reactions.
