PV = nRT

R = 0.08206 L atm
 mol K

R = 62.36 L torr
      mol K

1 atm = 760 torr = 101,325 Pa

STP = 1 atm & 0oC

ΔE= q + W

work = - PΔV

ΔH = ΔE + PΔV

1 calorie = 4.184 J

H2O Cp.= 1 cal/goC

qp (gained) = -qp (lost)

qp = Cp x mass x ΔT

qv = Cv x ΔT

oC = (oF-32)/1.8

oF = 1.8oC + 32

K = oC  + 273.15
