Question: In which of the following processes is the enthalpy change equal to the heat absorbed by the system at constant pressure? (2019)

Options:

Correct Answer: Isobaric process

Exam Year: 2019

Solution:

In an isobaric process, the enthalpy change is equal to the heat absorbed by the system at constant pressure.

In which of the following processes is the enthalpy change equal to the heat absorbed by the system at constant pressure? (2019)

In which of the following processes is the enthalpy change equal to the heat absorbed by the system at constant pressure? (2019)

Step 1: Understand what enthalpy is. Enthalpy is a measure of the total heat content of a system.
Step 2: Know what an isobaric process is. An isobaric process is a process that occurs at constant pressure.
Step 3: Learn the relationship between enthalpy change and heat. At constant pressure, the change in enthalpy (ΔH) is equal to the heat (q) absorbed or released by the system.
Step 4: Conclude that in an isobaric process, the enthalpy change is equal to the heat absorbed by the system.

Enthalpy Change – Enthalpy change (ΔH) is the heat content of a system at constant pressure, indicating the heat absorbed or released during a process.
Isobaric Process – An isobaric process is a thermodynamic process that occurs at constant pressure, where the heat absorbed by the system is equal to the change in enthalpy.
