You are doing a peer review of a science experiment. The paper claims that an increase of pressure requires a greater addition o
Rus_ich [418]

This is true because as thermal energy increases, molecules move faster and liquids are turned into gas.

States of matter is determined by the amount of energy possessed by the particles. Particles of a solid has the least amount of energy, liquid particles have more energy than solid particles while gas particles possess the highest amount of energy.

To increase the pressure of a substance, greater thermal energy is added to the substance by heating it up. This heat causes the molecules of the liquid to become more energetic and move faster .

As this occurs, intermolecular forces between the substance is broken as the liquid is converted to gas. The pressure. The energetic gas particles collide faster with the walls of the container thereby increasing the pressure.
