- Slide 1
- Magnitude of Expansion of Solids, Liquids and Gases Examples of Expansion Summary
- Slide 2
- Slide 3
- When molecules are heated they move far apart from each other This causes the material to expand Expansion Increase in size of a material due to added heat Contraction Decrease in size of a material when heat is removed
- Slide 4
- Let us look at 3 videos on the example of expansion and contraction
- Slide 5
- Bimetallic strip as thermometer
- Slide 6
- Liquid Expansion as thermometer Road expansion gaps
- Slide 7
- Tyre Fitting Opening a Jar
- Slide 8
- All materials expand Solids have linear expansion Varies among materials Liquids and Gases have volume expansion Varies among materials
- Slide 9
- Solid expansion< liquids< gases When a material changes from solid to liquid, volume does not change much Density is almost the same When a liquid changes to gas, the volume expansion is about 1000 times more Density is divided by 1000
