Generally, yes. The atoms in a substance move around much less the cooler they are, so the substance takes up less space.
is it when thet get smaller
Spring Meterials is High carbon steel. Total Carbon 0.5%. Vahical/Engine spring meterials crominium or Vanadium.
Sinile
what does the term mean smart materials
If the lava has cooled fast, the Cristal's will be smaller. If the lava cooled slowly, the crystals will be big
Most 2 cycle outboards are in fact water cooled. There were a few air cooled models, in the smaller hp range, produced years ago. Though there may be an air cooled engine in current production, I am not aware of it.
Metals, like most solids will contract when cooled. When cooled the atoms or molecules slow down, vibrating less often, causing a smaller average separation between them.
When heated it get larger and when you freeze it the matter gets smaller with an exeption to ice
Because crystals in granite had more time to form as the magma cooled slowly. Crystals that form on the surface are smaller because they cooled really quickly.
endoplasmic reticulum
Motorcycles and Aircrafts are two of the main vehicles that uses an air cooled engines. They use this feature since they normally have smaller engines then a normal moving vehicle.
Dielectric meterials are good insulator materials
