There are three states of matter. I.e Solid, Liquid and Gas. Gas is one of the classical state of matter. The word “gas” was first used by Flemish chemist, J.b Van Helmont in early 17th century.
The gaseous state of matter can be found between the liquid and plasma state.
Here you can find some questions related to gas, Boyle’s and Charle’s law along with their answers:
1. Which of the following statements is not correct about the states of matter?
(a) Molecules of solids are least energetic
(b) Molecules of gases have least energy
(c) Molecules of liquids have slow molecular motion
(d) Inter-particle forces are maximum in case of solids
2. What is not true statement about gaseous state?
(a) They are highly compressible
(b) They are very little compressible
(c) Thermal energy is equal to molecular attraction
(d) They exert pressure on the walls of the vessel due to collisions.
3. Which is the process of separation of individual gases from the gaseous mixture?

5. Among the plots of P vs V, as given below which one corresponds to Boyle’s law?
6. Which of the following plots will be linear with slope equal to zero in case of ideal gas?
(a) V vs T at constant P
(b) P vs T at constant V
