Answer to Question #169172 in General Chemistry for Bee

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 = 0.75L , T₁ = 27⁰C ,V₂ = ? , T₂ = 22⁰C

V₁/T₁ = V₂/T₂

0.75/27 = V₂/22

V₂ = (0.75×22)/27

V₂ = 0.61 L
