Two flasks of equal volume connected by a narrow tube of negliglible volume are filled with `N_(2)` gas. When both 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 an ice-water mixture keeping the other in boiling water. |

Answer» Temp. of the gas when both the flasks are immersed in boiling water`=100^(@)C=373" K"`. Pressure=0.5 atm Average temp. of the gas when one flask is immersed in ice and the other in boiling water `=(0+100)/(2)=50^(@)C=323" K"` As volume remains constant, `(P_(1))/(T_(1))=(P_(2))/(T_(2))` `(0.5)/(373)=(P_(2))/(323) " or " P_(2)=(323)/(373)xx0.5=0.433" atm"`. |
