b) Are the atoms still in their crystalline pattern even though they're moving? Yes 4) Heat the solid Neon to 20 K. What is this temperature in Celsius? -253°C a) What happens to the motion of the atoms? Getting faster b) Are the atoms still in the crystalline pattern? Yes 5) Heat the Neon to 30 K. What is this temperature in Celsius? -243°C a) The atoms are sliding past each other a.A) not moving. a.B) vibrating about a fixed position. a.C) sliding past each other. a.D) moving independently around the container. b) What state does this represent? Liquid Every now and then one atom gains enough energy to break free from the group. This is called a vapor. 6) Heat the Neon to 60 K. What is this temperature in Celsius? -213°C a) The atoms are moving independently around the container. a.A) not moving. a.B) vibrating about a fixed position. a.C) sliding past each other. a.D) moving independently around the container. b) What state is this? Gas c) Are all of the atoms moving at the same speed? No d) Does one individual atom always go the same speed? No e) Temperature corresponds to the average KE (or speed) of the atoms. 7) Heat the Neon to 120 K. a) On average, the speed of the atoms is twice the speed of the atoms at 60 K. a.A) half a.B) twice a.C) sixty times a.D) the same as 8) Look at water as a gas. The molecules now have two types of motion. Linear and rotational. 9) Look at water as a solid. Notice the
