A balloon originally had a volume of 6.63 L at 86 °C and a pressure of 684 torr. The balloon must be cooled to __________°C to reduce its volume to 6.03 L (at constant pressure). Express answer to the tenth decimal place
P1/T1 = P2/T2. Don't forget to use T in Kelvin. After find T, convert from Kelvin to celsius.
