a balloon is filled to a volume of 7.00 x 10 to the second mL at a temperature of 20.0 degrees celcius. the balloon is then cooled at a constant pressure to a temperature of 100 k. what is the final volume of the balloon?
(V1/T1) = (V2/T2)
T1 must be changed from CELSIUS (note the spelling) to kelvin.
