Thermal Expansion
Thermal Expansion
- the tendency of matter to change in volume in response to a change in temperature, through heat transfer
Particles expand when they are heated. They contract or get smaller when they are cooled.
Gas-particles contract
Liquid-particles slide over each other
Solid-particles vibrate
Power Line
On a hot day the power line sags because the line expands
Jar
Warm water was ran over the jar and the lid wouldn't fit anymore because it expanded.
Train Track
Tracks expand and cause danger for the train.
Thermal expansion caused by the warming of the oceans and the loss of glaciers due to increased melting is the cause of why oceans rise and expand. The ocean expansion can effect us and cause flooding some places for the people that live by the ocean and cause them to lose their homes. It could have an effect on life making land turn to water and overcrowding could occur. We have evidence of the ocean rising causing the tides to go further inland and over-flooding. I think that scientists have evidence of the ocean rising and that it is a true fact about ocean expansion.
