In an adiabatic process the quantity which remains constant is :
1 total heat of system
2 temperature
3 volume
4 pressure
Explanation:
A In an adiabatic process no transfer of heat take place from the system to the surrounding neither in case of expansion nor during compression. Thus, we can say that in an adiabatic process, the quantity which remains constant is the total heat of the system.

The enthalpy change of a chemical reaction in which 1 mole of a pure substance is formed from the free elements in their most stable states under standard state conditions is called
1 Molar enthalpy of vaporization
2 Standard enthalpy of fusion
3 Standard enthalpy of vaporization
4 Standard molar enthalpy of formation
Explanation:
D The enthalpy change of a chemical reaction in which 1 mole of a pure substance is formed from the free elements in their most stable states under standard state condition is called standard molar enthalpy of formation. Molar enthalpy of vaporization is the amount of energy needed to change one mole of a substance from the liquid phase to the gas phase at constant temperature and pressure.
