I was reading about enthalpy$^*$ when I thought that if it is possible for the gases undergoing a reaction to be supplied heat while keeping the pressure and temperature constant and just allowing it's volume to change, is it theoretically possible to supply heat to gases undergoing a reaction by keeping the temperature and volume constant and allowing only the pressure to change?
My intuition says that this is not possible, since pressure is the result of molecule collision. On heating, the collisions get more vigorous hereby increasing the pressure. But the increased molecular vibrations would cause a rise in temperature. I am not sure how correct my intuition is and would like someone more knowledgeable than me to weight in.
My question is not a duplicate and nor related to this question
$* $: In my book, enthalpy is defined as:
heat evolved or absorbed in a reaction at constant temperature and constant pressure
