Two identical rooms in a perfectly insulated house are connected by an open doorway. The temperature in the two rooms are maintained at different values. The room which contains more air molecules is :

A

the one with higher temperature

B

the one with lower temperature

C

the one with higher pressure

D

neither since both have same volume

Text Solution

Verified by Experts

The correct Answer is:
B
PV=nRT
Since both the rooms same volume and are connected, so they will have same pressure
PV=nRT=constant `rArr nT =("Constant")/(R )`=constant
If T is more n has to be less
Hence, lower the temperature, more the number molecules.
