Chapter 7 Glossary - Physical and Chemical Change

A change of state where a liquid is heated and changes to a gas within the liquid

• Boiling

• Condensation

• Melting

• Evaporation

The chemical reaction in plants that converts carbon dioxide and water into oxygen and glucose using energy from the Sun

• Crystallisation

• Respiration

• Plant Synthesis

• Photosynthesis

Contraction is

• an increase in size

• a decrease in size

• a change of state

• the process of diffusion

Expansion is

• An increase in size

• a decrease in size

• a change of state

• the process of diffusion

The substance found in plant leaves that makes leaves green and collects energy from the sun for photosynthesis

• Chloroplast
