Matter going from a solid to a liquid went through what phase change?
Melting (fusion)

The boiling point of a liquid is when it will turn into a solid.
False

Give an example of a solid turning into a liquid (melting).
Ice melting into liquid water.

Density is how heavy an object is.
False, density is how much stuff (mass) is packed into a certain space (volume).

Explain how the particles in a gas are different from the particles in a solid.
The particles in a gas a further apart than in gases, they are moving faster than the particles in a solid, and they have weaker intermolecular forces.
500
Explain what happens to the particles of matter that go through freezing (solidification).
The particles will come closer together since they are gaining attraction from the loss of heat, and will start to move slower.
500
When the volume of matter changes during a phase change, the mass will also change.
False, even if the volume changes during a phase change the mass will always stay the same.

Shane Filled up his engine coolant last night before he went to bed. He just checked the levels before he left in the morning, and it has overflowed. What happened?
It might've been colder at night, so in the morning when it warmed up the coolant expanded because of the increase in heat.
