X and Y are two equal size containers. X contains a gas A at a temperature `75^@ `C and Y contains a gas B at a temperature `40^@ `C. Each gas behaves as an ideal gas and specific heat at constant pressure for both gases has the same value.
From the given information, we can conclude that

Options

A. the molecules in container X are moving as fast as those in container Y.
B. the molecules in container X are moving faster than those in container Y.
C. the molecules in container Y are moving faster than those in container X.
D. no possibility can be ruled out, that is, molecules in X could be moving faster than those in Y or the mole cules in Y could be moving faster than those in X.

Answer

D
