Answer:
Enthalpy of gas is greater than that of liquid
Step-by-step explanation
Ethyl chloride (C2H5Cl) boils at 12 degrees Celsius. When liquid C2H5Cl under pressure is sprayed on a room-temperature (25 degrees Celsius) surface in the air, the surface is cooled considerably.
this preamble could precede the question
Enthalpy
it can defined as the ability of a substance to change at constant pressure, enthalpy tells how much heat and work was added or removed from the substance. Enthalpy is similar to energy, but not the same. When a substance grows or shrinks, energy is used up or released.
The total heat content of a system is known as Enthalp.it is a thermodynamic property. It is the internal energy of the system plus the product of pressure and volume.
