On a day when the partial pressure of water vapor remains constant, what happens as the temperature rises?

It is the energy emitted by the matter in the form of electromagnetic waves as a result of the changes in the electronic configurations of the atom or molecules

It is the energy possesses by the system as a result of its elevation with respect to the gravitational acceleration of the earth.

It is the transfer of energy from the more energetic particles of substance to the adjacent less energetic ones as a result of interactions between the particles.

It is defined as the amount of light output in lumens per W of electricity consumed

A piston cylinder device initially contains 0.8 m^3 of air at 110kPa and 80°C. The air is now compressed to 0.2 m3 in such a way that the temperature inside the cylinder remains constant. Determine the work done during this process.
