Water Phase Change

[Anish Natarajan 4G]

Can someone reiterate how water as a gas has more energy as water as a liquid when they are booth at 100 degrees C?

[Maggie Eberhardt - 2H]

I think gases have more energy because the molecules move faster and do not have a defined space they take up

[Andrew F 2L]

I think it is because gas particles have more room to move and there is more kinetic energy because the particles are hitting against each other due to the more space they have to work with

[Aiden Metzner 2C]

It is because there is energy required to break bonds between water molecules. The hydrogen bonds in water are strong so it takes a lot of energy, therefore more energy is stored in gas at the same temperature than at liquid.

[Joowon Seo 3A]

There needs to be energy required to break the hydrogen bonds in between the water molecules.

[CalvinTNguyen2D]

Because the molecules of water are held together by hydrogen bonding, it takes a large amount of energy to break those bonds and change its phase; this energy is reflected in the gas phase with its high kinetic energy

As mentioned above, the molecules of water are held together by hydrogen bonding; breaking those bonds require a great amount of energy.
