The explanation of Thermal Expansion.
What else can I help you with?
When matter is heated does it contract?
No, when matter becomes heated it always expands, meanwhile when matter becomes cool it always contracts.
Why does skin get tight after swimming?
Probably because heat expands and cool contracts! That's the same term!
What is the purpose of the overflow tank?
The coolant expands when heated, contracts when cool. The coolant reservoir gives the coolant a place to come and go as needed.
Why do mechanics tell you to check your car tires in the spring and in the fall?
The air in your tires expands in the spring and contracts in fall. On a cool day in fall your tire pressure will be low.
What happens to metal when it gets cool?
It contracts
What causes the heat to expand?
heat does not necessarily expand.. the varying temperatures causes different elements that make up an object to expand or contract e.g. tar on the road expands in the heat and contracts in the cool and therefore cracks are formed in the road.
What is really cool about water?
Water is the only liquid that expands when frozen.
When air rises does it cool down?
Yes. (As the density falls, it expands.)
What does thermal expansion of water mean and why is it relevant to the rising sea levels?
Thermal expansion relates to how things expand when they heat up and contract when they cool down. This also applies to the water in the ocean. The hotter it is, the more it expands, making sea levels rise.
What makes meteors cool?
Any object that is hotter than its surroundings will cool down over time.
Who is a hotter Milf Kris Jenner or Kathy Hilton?
Kathy Hilton definitely.. Kris Jenner's a cool mom but Kathy's hotter
Does warm air contract?
Heat is caused by molecules vibrating and hitting one another. The hotter the air the more the molecules vibrate and the bigger space each molecule needs. This causes the air to expand and its density to fall. As air cools, the vibrations slow down and the molecules need less room. This causes the air to contract and its density will go up.
