"what does this observation tell us about the enthalpy of c2h5cl(g) as compared with the enthalpy of c2h5cl(l)

Enthalpy of gas is greater than that of liquid

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.

H=U+PV1

h let me think about that

a graduated cylinder.
