internal energy
-
because the atoms have space between them, they have potential energy
at higher temps, atoms gain more thermal energy, they move faster which means more kinetic energy and more internal energy
thermal energy transfer
transferring methods
conduction: works in solid, the thermal energy gets transferred between particles via bumping into eachother
convection: works in liquid and gas, the hot air/liquid rises up and cools down, then it drops down and heat up. repeat
radiation: works in vacuums, shoots out particles with thermal energy stored in it through a vacuum
greenhouse
when sunlight enters a greenhouse, it heats the inside up and trap the heat in
heat expansion
heat expansion in solids
when solids gain therm energy, its particles gain kinetic energy and the solid expands
