Explain phase changes and the relationship between kinetic energy and intermolecular forces.

If we increase the temperature, the average kinetic energy increases, and that means the molecules are more likely to have enough kinetic energy to go into or stay in the gas phase. (Thus, they are called intermolecular forces, to separate them from the forces inside molecules that hold the molecules together.)

Explanation:

here you go:)

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
