When we boil water, some of the water evaporates into....
steam
Gas
Phase changes occur when you add or remove
heat energy
What causes the increase in volume when heat is added to matter?
Particles get further apart/ weaker intermolecular bonds
Is liquid water or ice more dense?
Liquid water
This state of matter has no definite shape or volume
Gas
