It is said that "
gases assume the shape and volume of containe
r".
Suppose some amount of gas is passed in an
iron container
of dimensions [ 50 cm * 20 cm] and of 1 kg. Let the volume found be x dm
3
. Now the same amount of gas is passed in a
plastic container
of same dimension but of
500 gm
. So will the volume of gas remain same or will it change?
