What are some effects of Heat Gain and Heat Loss in our daily lives?

Expansion and Contraction

  • Things expand or become bigger when heated. The increase in size or expansion is due to heat gain.
  • Things contract or become smaller when they cool down. The decrease in size or contraction is due to heat loss. 
  • Most solids, liquids and gases expand when heated and contract when cooled.
