Question
A helium balloon has a volume of 18.1 L
when the pressure is 1.045 atm and the temperature is 19 ◦C. The balloon is cooled at
a constant pressure until the temperature is
−16◦C. What is the volume of the balloon at
this stage?
Answer in units of L.

PV=kT
since P is also constant,
V/T is constant. So you need
V/(273-16) = 1.045/(273+19)
since P is also constant,
V/T is constant. So you need
V/(273-16) = 1.045/(273+19)
