D) moving independently around the container.

b) Are the atoms still in their crystalline pattern even though they're moving? 4) Heat the solid Neon to 20 K. What is this temperature in Celsius?

a) What happens to the motion of the atoms?

b) Are the atoms still in the crystalline pattern?

5) Heat the Neon to 30 K. What is this temperature in Celsius? a) The atoms are … A) not moving. B) vibrating about a fixed position. C) sliding past each other. D) moving independently around the container.

b) What state does this represent?

Every now and then one atom gains enough energy to break free from the group. This is called a vapor.
