Pressure of an ideal gas, contained in a closed vessel, is increased by 0.4\% when heated by 1 . Its initial temperature must be:

  1. 2500 K
  2. 25
  3. 250
  4. 250 K

Answer

(4) 250 K

Solution

Closed vessel volume constant P T

PP = TT

0.4100 = 1T (a rise of 1 = a rise of 1 K)

T = 250 K

Answer: (4)
