Question

An open vessel at 27°C is heated until three fifth of the air has been expelled. Assuming the volume of the vessel remains constant the temperature to which vessel has to be heated is

Correct answer: (C) 750 K. From question, pressure and volume are constant T_1=273+27=300K n_1=1, n_2=1-3/5=2/5 n_1/n_2=T_2/T_1 So T_2=n_1T_1/n_2=(5×300)/2=750K .
