In an isobaric process, expansion should result in a decrease in pressure. which of the following must be added to the system to prevent this pressure drop and maintain isobaric conditions? a. heat (q) b. work (w) c. internal energy (u) d. none of these

Option a. Heat (Q)

Explanation:

In an isobaric process, the pressure of the system does not change and remains constant. It is a thermodynamic process which is usually attained by the contraction or expansion in volume such that it do not effect the maintained pressure of the system that would result from transfer of heat and thus isobaric conditions are maintained.
