Presentation transcript:

Thermal Expansion

Expansion Many substances expand when heated When heated, the particles (atoms or molecules) in a substance vibrate more This means they need more space So the substance expands Heat

Important note! The particles in a substance do not expand themselves! Heat Particles are the same size

Contraction The opposite happens when most substances are cooled The particles vibrate less They need less room The substance contracts Cools

Thermal Expansion There are 3 stations around the room. Read the instructions/complete the task/answer the questions at each station. You may go around in any order and will have 4 minutes at each station You must fill in the worksheet for each station and move on immediately when told to

Additional Questions Different materials expand by different amounts for a given temperature change. Considering this, explain why steel can be used in concrete to reinforce structures Explain in detail how hot air balloons work
