Presentation Transcript

Slide 1: 

States of Matter Solids, Liquids and Gases Preety Chawla

Slide 2: 

Three states of matter solid liquid gas At room temperature most substances exist in one of three physical states.

Slide 3: 

Properties of solids, liquids and gases

Slide 4: 

The Particle Model The difference between solids, liquids and gases can be explained by the… particle model All substances are made up of particles. The particles are attracted to each other. Some particles are attracted strongly to each other and others weakly. The particles move around. They are described as having kinetic energy. The kinetic energy of the particles increases with temperature.

Slide 5: 

Particles in Solid

Slide 6: 

Particles in a liquid

Slide 7: 

Particles in a liquid

Slide 8: 

Particles in a gas

Slide 9: 

Qus. :- Define Matter. 2.Qus. :- How can you physically classify matter? 3.Qus. :- Give two examples of each state of matter i.e. solid, liquid and gas?

Slide 10: 

Diffusion occurs in liquids and gases but hardly at all in solids. What is diffusion? Diffusion is the movement of particles that allows them to spread out and mix with other particles. For example, the smell of aftershave or perfume diffuses and is detected by people on the other side of the room. Use the particle model to explain these facts about diffusion: Diffusion happens more quickly for gases than for liquids. Diffusion happens more quickly at warm temperatures than at cooler temperatures.
