10 g of a gas at STP occupies a volume of 2 L . At what temperature will the volume be doubled, if pressure and amount of the gas remains constant?

Options

  1. A273   K
  2. B546   K
  3. C- 273   K
  4. D546 ° C

Correct answer

B. 546   K

Step-by-step solution

At constant pressure, the volume is proportional to the absolute temperature. V 1 T 1 = V 2 T 2 Here, V 1 = 2   L     T 1 = 273   K   STP V 2 = 4   L   T 2 = ? Putting all the values, we get T 2 , 2 273 = 4 T 2 T 2 = 546   K
