Question

Which of the following terms encompasses all the heat input required to take a test item, such as a chair, from an intact entity at room temperature to a fully vaporized state?

A) Enthalpy
B) Heat of formation
C) Latent heat
D) Standard enthalpy

Answer 1

Enthalpy is the term that refers to the total heat content of a system at constant pressure, covering the heat input needed for vaporization of an object.

Step-by-step explanation:

The term that encompasses all the heat input required to take a test item from an intact entity at room temperature to a fully vaporized state is Enthalpy (Option A). Enthalpy (H) involves the heat content of a system at constant pressure. When we consider the heat input required to vaporize a substance, we are interested in the heat that is absorbed or released by a system, which corresponds to an enthalpy change at constant pressure, or ΔH.
