system <-> surroundings "aqueous"
(heat in/out,temp +/-)
physical change chemical change
ice melting (in,+) cold pack (in,-)
making ice (out,-) match burning (out,+)
heat transferred [J|calories] = (mass) (specific heat capacity) (change in temperature)
[J/g-K] (notice the notation in place of [J/g/K]) metals and gasses are same 20-30
[J/mole-K]
