Solid, Liquid And Gases- Triple

Question 1

Particle theory

Answer 1

Temperature of gas (kelvin) is proportional to the average kinetic energy of particles

Question 2

In a sealed container

Answer 2

Pressure / temperature (kelvin) = constant

p1 /t1 = p2 / t2

Question 3

Solid

Answer 3

Strong forces of attraction hold the particles close together on a fixed, regular arragement and can only vibrate

Question 4

Liquid

Answer 4

1. Weaker forces of attraction between the particles
2. Particles are close together but can move past each other and form irregular arrangements
3. They have more energy than solids and move in random directions at slow speeds

Question 5

Gas

Answer 5

1. Almost no forces of attraction
2. They have more energy than solids and liquids
3. They are free to move and travel in random directions and at high speeds

Question 6

Evaporation

Answer 6

Is when particles escape from a liquid and become gas particles
