Equal masses of oxygen and helium gases are supplied equal amount of heat. Which gas will undergo a greater temperature rise and why?

Answer»

Solution :Heat SUPPLIED to oxygen `=` Heat supplied to Helium
`mc_(1)DeltaT_(1)=mc_(2)DeltaT_(2)`
`(DeltaT_(1))/(DeltaT_(2))=(c_(2))/(c_(1))`, As `CXX(1)/(m)`, `m=` molecular mass
`(DeltaT_(1))/(DeltaT_(2))=(c_(2))/(c_(1))=(m_(1))/(m_(2))`, As `m_(1) gt m_(2)`
`DeltaT_(1) gt DeltaT_(2)`
