Kinetic Theory of Matter and Gas Laws - Explained
In this video lesson, we explored the kinetic theory of matter and the fundamental principles governing the behaviour of gases.
Learning Objectives:
By the end of this video lesson, the learners should be able to:
- mention the three states of matter,
- explain the properties of each of the states of matter,
- state and define the different changes of states of matter,
- understand the kinetic theory's explanation of matter's bahaviour
- state and explain the kinetic theory's principle
- state the gas laws and show their mathematical and graphical representations,
- applying the gas laws to predict pressure, volume and temperature changes,
- use the ideal gas equations to solve problems,
- distinguish between ideal and real gases, and
- calculate partial pressures using Dalton's law.

*TRIAL. What will be the new volume(v) if the new pressure is halved and the initial pressure the same.
Using S.T.P/ Boyle's law
P1V1= P2V2
P1 = 760mmHg
P2 = ( halved) =380mmHg
V1= 22.4dm^3
V2 = ?
V2 = p1v1/p2
= 760* 22.4 /380
= 44.8dm^3

please the topics on chemistry and physics should be completed. Jamb exam is fast approaching

no1.
n=5 T=-33+273=240 P=10atm R=0.082
Then PV=nRT
10×V=5×0.082×240\10
V=9.84dm³.
NO2.
1/2×10atm=5atm
then PV=nRT
5×V=5×0.082×240/5
V=19.68dm³
