Answers

Answered by jaspreetkhaira

Enthalpy describes a state of energy of a gas - essentially the heat energy and pressure energy content of a gas: H = U + PV. A change in enthalpy denotes a change in energy content of the gas, ie. some combination of change in temperature, pressure and/or volume of the gas.

sanabegum: And wht is enrgy?

jaspreetkhaira: In physics, energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.

DIFFERENCE BETWEEN ENERGY AND ENTHALPY.

Energy of a chemical system is called the enthalpy ( H). It is easiest to think of enthalpy as the heat energy that is stored in the chemical bonds of a substance.

A change in enthalpy denotes a change in energy content of the gas, ie. some combination of change in temperature, pressure and/or volume of the gas.
