A gas at 298 K is shifted from a vessel of 250 cm3 capacity to that of 1L capacity. The final pressure of the gas will

A.become double
B.becomes four times
C.decrease to half of the original value
D.decrease to one-fourth of the original value✓ Correct
Explanation

This numerical is based on the Boyle’s Law 1 P V where, P= pressure and V=Volume So, 1 1 2 2 constant PV PV PV (At constant T and n) Let us consider initial pressure=P 3 1 3 2 1 1 2 2 2 2 2 250 1 1000 250 1000 4 4 V cm V L cm PV PV P P P P P P >> x x >> Thus the correct option is (d) decrease to one-fourth of the original value
