Can heat be added to a substance without causing the temperature of the body of rise? If so does this contradict the concept of heat as energy in the process of transfer because of temperature differece?

Explanation

Yes, heat can be added to a body without causing the temperature of the body to rise as in the case of latent heat being added to cause a change of state of the body or isothermal process. This does not contradict the concept of heat as energy in transit due to temperature difference because there is a big difference of temperature between the substance and the source from which heat is received by the substance and in this case, the heat supplied increases the intermolecular distance.
