Same gas is filled in two vessels of the same volume at the same temperature. If the ratio of the number of molecules is \( 1: 4 \), then
(a) The r.m.s. velocity of gas molecules in two vessels will be the same.
(b) The ratio of pressure in these vessels will be \( 1: 4 \)
- (c) The ratio of pressure will be 1:1
(d) The r.m.s. velocity of gas molecules in two vessels will be in the ratio of \( 1: 4 \)
(a) \( a \) and \( c \) only
(b) \( b \) and \( d \) only
(c) \( a \) and \( b \) only
(d) \( c \) and \( d \) only
