Question

7 Which of the following statements is wrong for gases?
4 Confined gas exerts uniform pressure on the
walls of its container in all directions
0 Volume of the gas is equal to volume of container
confining the gas
(3) Gases do not have a definite shape and volume
(4) Mass of a gas cannot be determined by weighing
a container in which it is enclosed​

Answer 1

I think it's (4)

Because all the other options seem correct

And what other way is there to measure weight of a gas?

Answer 2

Your second option is wrong!!

Volume of gas isn't equal to volume of container confining it . In fact volume of gas is not definite due to its highly compressible nature.

Hope it helps you out!
