0.40 g of helium in a bulb at a temperature of T ~K had a pressure of p atm. When the bulb was immersed in water bath at temperature 50 K more than the first one, 0.08 g of gas had to be removed to restore the original pressure. T is

Step-by-step solution

As pressure and volume remains constant, aligned n₁ T₁ & =n₂ T₂ n₁ & = 0.4 4 =0.1, T₁=T ~K n₂ & = 0.40-0.08 4 =0.08, T₂=(T+50) K aligned On putting the values, array ll & 0.1 T=0.08 (T+50) or & 0.1 ~T =0.08 T=4 or 0.1 ~T -0.08 ~T =4 or & 0.02 T=4 or T=200 ~K array
