Two flasks of equal volume are connected by a narrow tube of negligible volume and are filled with `N_(2)` gas. When both the flasks are immersed in boiling water the gas pressure inside the system is 0.5 atm. Calculate the pressure of the system when one of the flasks is immersed in ice water while the other flask in boiling water.

Explanation

Temperature of the gas when flasks are in boiling water =100+273=373K and presure=0.5 atm
The average temperature of the gas when one flask is in ice and other in boiling water.
`=(0+100)/(2)=50^(@)C=50+273=323K`
`therefore (P_(1))/(T_(1))=(P_(2))/(T_(2)) or, (0.5)/(373)=(P_(2))/(323) or, P_(2)=0.433atm`.
