Question

A balloon is inflated with helium to a volume of 0.75 L at 27°C. The balloon was found several  hours later, snd the temperature had dropped to 22°C. What would be the volume of the balloon when found, if no helium had escaped? 

Answer 1

V₁/T₁=V₂/T₂;

V₂= V₁*T₂/T₁=0.75*22/27=0.61 L

Answer:  the volume of the balloon is 0.61 L
