When ice melts, a solid is changed into a liquid. What causes this change?

(6.P.2.2)

• The atoms are moving slower due to gaining heat.

• The atoms have less energy and come together.

• A solid has a definite shape and a definite volume.

How are atoms affected when the temperature of an object is decreased?

(6.P.2.2)

If a piece of cork and a rock that are the same size are dropped into a cup of water one floats and the other sinks. Why does this happen?

(6.P.2.3)

• The cork has fewer atoms in the same amount of space as the water it is in so it floats.

• The cork has holes that let the water in so it floats, and the rock does not have holes so it sinks.

• The rock has fewer atoms in the same amount of space as the cork so it sinks.

• The rock weighs more than the cork so it sinks.
