Answer to Question #69939 in Molecular Physics | Thermodynamics for Devon

Question

When the pressure that a gas exert on a sealed container changes from torr to 456 torr, the temperature changes from 150°GC to 75.0°C ?

Answer 1

If the process takes place at a constant volume, then:
P_1/T_1 =P_2/T_2 ;
P_1=(T_1∙P_2)/T_2 ;
T1 = (150 + 273) K = 423 K;
T2 = (75 + 273) K = 348 K;
P2 = 456 torr;
P_1=(423∙456)/348=554.3 torr.
Answer: 554.3 torr.
