A fixed chamber isolated from surrounding is divided into two equal
half A and B as shown in the figure. Part A contains one mole of Oxygen and Part B contains one mole of helium, the separator C is thermally conducting and kept fixed. Initial temperature of oxygen
chamber is 600 K and that of helium 300 K. Specific heat capacity of
separator and chamber is negligible. Choose the correct statement.
(A) change of temperature of helium is equal to change in temperature of oxygen
(B) change in internal energy of helium is equal to 200 R joule (R represents the value of the gas
constant in SI)
(C) temperature of oxygen in steady state condition is 487 K (approx)
(D) temperature in steady state can't be calculated
