Phase Changes QUIZ

You have decided to start sealing all your letters with glittery wax because you are so "cool". Which answer BEST explains what you must do to make the SOLID wax a LIQUID?

• In order to make the SOLID wax a LIQUID you must ADD HEAT ENERGY by putting the wax in the FREEZER.

• In order to make the SOLID wax a LIQUID you must ADD HEAT ENERGY by putting the wax over a FLAME.

• In order to make the SOLID wax a LIQUID you must REMOVE HEAT ENERGY by putting the wax in an OVEN.

You have dropped your popsicle and are watching it become a LIQUID. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule MOVEMENT has changed?

• The PHASE CHANGE that has occurred is CONDENSATION and the molecule MOVEMENT has become FASTER.

• The PHASE CHANGE that has occurred is EVAPORATION and the molecule MOVEMENT has become SLOWER.

• The PHASE CHANGE that has occurred is MELTING and the molecule MOVEMENT has become FASTER.

You are drinking a cold drink on a hot day when you notice LIQUID water has collected on the can. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule ARRANGEMENT has changed?

• The PHASE CHANGE that has occurred is CONDENSATION and the molecule ARRANGEMENT has become CLOSER and energy has been released.

• The PHASE CHANGE that has occurred is FREEZING and the molecule ARRANGEMENT has become CLOSER and energy has been absorbed.

• The PHASE CHANGE that has occurred is EVAPORATION and the molecule MOVEMENT has become FASTER and energy has been released.

You are relaxing on some grass when you notice LIQUID water droplets have begun to seemingly disappear off the grass leaves. Which answer BEST explains what PHASE CHANGE has occurred AND how the molecule ARRANGEMENT has changed?

• The PHASE CHANGE that has occurred is EVAPORATION and the molecule ARRANGEMENT has become FARTHER APART.

• The PHASE CHANGE that has occurred is FREEZING and the molecule ARRANGEMENT has become CLOSER.

• The PHASE CHANGE that has occurred is MELTING and the molecule MOVEMENT has become FASTER.

You watch your science teacher put a balloon in a bowl of liquid nitrogen and see the balloon has shrunk like a raisin. Which answer BEST explains how you know if HEAT ENERGY been ADDED or REMOVED.

• HEAT ENERGY has been ADDED. I know this because the balloon has become LARGER meaning the molecule ARRANGEMENT is FARTHER APART.

• HEAT ENERGY has been REMOVED. I know this because the balloon has become SMALLER meaning the molecule ARRANGEMENT is CLOSER.

• HEAT ENERGY has actually stayed the SAME. I know this because the balloon has NOT CHANGED meaning the molecule ARRANGEMENT is also NOT CHANGED.

Your teacher asks your group to discuss molecule MOVEMENT and molecule ARRANGEMENT in a SOLID. Each of your group members shares their answer. Decide who has the BEST answer.

• Eva says molecule MOVEMENT in a SOLID is SLOW and the molecule ARRANGEMENT is FAR APART.

• Ethan says molecules DO NOT MOVE in a SOLID and the molecule ARRANGEMENT is CLOSE.

• Maddie says molecule MOVEMENT in a SOLID is SLOW and the molecule ARRANGEMENT is CLOSE.
