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.
