@All.

When the gas is heated under constant pressure, it leads increase in the volume and as the gas is being heats it temperature increases due to change in internal energy q = δ (U) + WORKDONE.

Constant pressure, so volume may be changed and pdv work may happen so some part of the energy may be utilized to do pdv work and other part may be utilized to increase internal energy.

According to first law q = u+pv. So heat which is supplied its some part is used to inc its internal energy and some part is use to do work.

This is according to 1st law of thermodynamics.
