Question

Nitrogen vaporization of heat per gram __________?

Options:
A) Increases
B) Decreases
C) Remains constant
D) Fluctuates

Answer 1

The vaporization of heat per gram of nitrogen remains constant.The correct option is D.

Step-by-step explanation:

The vaporization of heat per gram of nitrogen remains constant.

When heat is added to a substance, it undergoes a phase change from a solid to a liquid and then to a gas. This phase change requires energy, and the amount of energy required per gram of substance is called the heat of vaporization. For nitrogen, the heat of vaporization remains constant at a specific temperature and pressure.

Therefore, the correct answer is option C) Remains constant.
