System
change
exothermic
releasing heat
smaller ΔH
endothermic
absorbing heat
greater ΔH
in the lab

system
whatever is being studied, you define system
open
mass transfer & heat transfer
closed
only heat transfer
isolated
no mass transfer or heat transfer
surroundings
everything outside of system
Heat Equation
Q = mcΔT
Q = heat (cal or J)
m = mass (g)
c = specific heat
J/g ^degree^ C
quantity of energy it takes to raise the temp of 1 g of a material by 1 degree C
ΔT = change in temperature
