Question: Which equation relates the change in enthalpy to heat at constant pressure?

Options:

Correct Answer: ΔH = q_p

Solution:

At constant pressure, the change in enthalpy (ΔH) is equal to the heat added to the system (q_p).

Which equation relates the change in enthalpy to heat at constant pressure?

Step 1: Understand what enthalpy (H) is. It is a measure of the total energy of a system, including internal energy and the energy required to make room for it in the environment.
Step 2: Recognize that when a system is at constant pressure, any heat added or removed from the system affects its enthalpy.
Step 3: Learn that the change in enthalpy (ΔH) is calculated by taking the final enthalpy minus the initial enthalpy.
Step 4: Know that at constant pressure, the heat added to the system (q_p) is equal to the change in enthalpy (ΔH).
Step 5: Write the relationship as an equation: ΔH = q_p.
