Kinetic Partivle Theory

Front 1

Describe What would happen to the particles of element C when it is cooled from 80°C to -10°C

Back 1

•Particles lose kinetic energy

•The movement slows down

• They came closer to one another until arranged in an orderly manner.

Front 2

The kinetic theory explains the properties of solids,liquids and gases in terms of the movement of particles. Liquids and gases both take up the shape of the container but a gas always fills the container. Explain this,using the ideas of the kinetic particle theory.

Back 2

According to kinetic particle Theory,the tiny particles in a gas are spread far apart because the forces of attractions between them are very weak.These particles have a lot of space between them. Thus it fills the container whereas in a liquid,the particles are still packed closely together but in a disorderly manner . They can move freely by sliding over another.

Front 3

Which gas carbon dioxide or sulfur dioxide would diffuse faster?Explain your choice.

Back 3

Carbon dioxide diffuses faster than sulfur dioxide,because the molecular weight of carbon dioxide is lesser than Sulfur dioxide.

Front 4

Two pieces of cotton wool,soaked and seperately in aqueous solutions of ammonia and hydrogen chloride are placed ends of a tube.Nearest to which positions A,B or C is the white solid formed

Back 4

C.Because the relative molecular mass of ammonia is smaller than the MR of HCL . Hence Ammonia particles are lighter and move faster than HCL gas particles

Front 5

The solid state.

Why does a solid have a fixed shape and fixed volume.

Back 5

The particles of a solid are held together by very strong forces of attractio. They cannot move Freely . They only have enough kinetic energy to vibrate and rotate about their fixed position.For this reason,a solid has a fixed volume .

A solid cannot be compressed since its particles are already very close to one another.
