2 balloons A and B of volume 600 ml and 1000 ml are taken at temperature 400 K. Max capacity of balloon A and B are 800 and 1200 ml resp. When the temperature is raised which balloon will burst first ?

V1/T1 = V2/T2. For A, it is

600/400 = 800/T2. Solve for T2

Do the same for the 800 to 1200(that's B). Compare T2 values.
