Which state of matter has particles (molecules) with the most energy?

Back

Gas

Front

What is the process called when solid carbon dioxide (dry ice) changes from solid to vapor?

Back

Sublimation

Front

Describe the motion of water molecules as ice changes from solid to liquid water.

Back

The molecules in the solid are in a rigid lattice and vibrate more rapidly. As the ice melts, the molecules in the liquid move more freely but are still attracted to each other.

What is the state of matter that has a definite volume but no definite shape?

Back

Liquid

Front

What occurs to the energy of molecules when a substance changes from a solid to a liquid?

Back

The energy of the molecules increases.
