The temperature of an open room of volume 30 m3 increases from 17°C to 27°C due to sunshine. The atmospheric pressure in the room remains 1×105 Pa. If Ni and Nf are the number of molecules in the room before and after heating, then Nf−Ni will be:
- 2.5 × 1025
- -2.5 × 1025
- -1.61 × 1023
- 1.38 × 1023
Answer
(C) -1.61 × 10 23
