In order for a liquid particle to become a gas it must: (choose all that apply)
1.overcome the attractive forces of other liquid particles
2.overcome the attractive forces of other gas particles
3.gain energy
4.lose energy

1.overcome the attractive forces of other liquid particles

3.gain energy

Explanation:

A phase change from liquid to solid occurs when heat energy is added to the system. The heat energy gives the liquid molecules more kinetic energy and the attractive forces between the particles are overcome. When the molecules of liquid gains sufficient energy, they are free to move in all directions that they want, thus becoming gases.
