Which one of the following statements is wrong for gases?

Answer»

Gases do not have a definite shape and volumne
Volume of the gas is EQUAL to the volume of the container confining the gas
Confined gas exerts uniform PRESSURE on the WALLS of its container in all directions
Mass of the gas cannot be determined by weighing a container in which it is enclosed

Solution :The mass of gas can be determined by weighing the container, FILLED with gas and again weighing this container after removing the gas. The DIFFERENCE beetween the two weights gives the mass of the gas.
