Chapter 6 test_review Science
This document provides a review of key concepts from Chapter 6 including: - Gases can change shape and volume while liquids have a definite volume but shape changes to fit their container. - Heat is the transfer of thermal energy between substances and temperature measures average particle kinetic energy. - Condensation is when a gas turns to a liquid and vaporization is when a liquid turns to a gas. - Density is mass per unit volume and pressure is force per unit area.
