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 temperatureB. the one with lower temperatureC. the one with higher pressureD. neither since both have same volume |

Answer» Correct Answer - 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. |
