heat
the flow of thermal energy from a warmer object to a cooler object (movement of thermal energy)
Thermal energy
total KE of particles in a system
Temperature
average KE of particles in a substance
system
substances experiencing exchange
surroundings
everything else
Universe
sytem+surroundings
endothermic
heat is absorbed by the system from the surroundings
exothermic
heat is released from the system into the surroundings
Physical energy
energy associated w/phase change… stored between molecules
chemical energy
energy associated w/ chemical changes.. stored in chemical bonds (within a molecule)
Breaking up bonds is hard to do
-breaking bonds requires energy
-forming bonds releases energy
specific heat
the amount of energy required to raise the temperature of 1g of a substance by 1 degree C (how much heat can an object absorb before it gets hot) (Joules/grams/*C)
