Changes of State Flashcards

All 6 cards in this deck

What is sublimation?

A change of state from solid directly to gas.

Which change of state is from gas to liquid?

Condensing.

True or false? When ice melts, the mass of water formed is less than the mass of the ice.

False. Mass is conserved in any change of state.

Why are melting, boiling and condensing physical changes rather than chemical changes?

No new substance is made — the change can be reversed and the material recovers its original properties.

Which change of state is from liquid to solid?

Freezing.

Which two changes of state are from liquid to gas?

Boiling and evaporating.
