Question

what is enthalpy ? explain it​

Answer 1

Explanation:

Enthalpy is a thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system. It reflects the capacity to do non-mechanical work and the capacity to release heat.

Enthalpy is denoted as H; specific enthalpy denoted as h. Common units used to express enthalpy are the joule, calorie, or BTU (British Thermal Unit.) Enthalpy in a throttling process is constant.

Answer 2

Answer:

The thermodynamic quantity equivalent to the total heat content of a system.It is equal to the internal energy of the system plus the product of pressure and volume.
