Sketch a graph to show the relationship between the pressure of a gas and its absolute temperature.
Important Questions on The Kinetic Model of Matter
Which states of matter are being described here? Complete the table.
The first example has been done for you.
| Description | State or states |
| Occupies a fixed volume | Solid, liquid |
| Evaporates to become a gas | |
| Takes the shape of its container | |
| Has a fixed volume | |
| May become a liquid when its temperature changes |
Label each arrow in the diagram below to show the name of the change of state.
Describe and explain the changes in the molecular structure of water, in the form of ice as it is heated until the water has become steam. Consider the arrangement of molecules.
Complete the table. In the first row, draw sketches of the three states of matter in terms of the arrangement of the particles and their movement. Then describe the three states, referring to the three criteria in the first column.
| State | Solid | Liquid | Gas |

| How close are particles to their neighbours? | |||
| How do the particles move? | |||
| Strength of forces between particles (strong/weak/zero) |
What is the word we use to describe the process of a liquid becoming a gas?
A mass of gas is at and a pressure of . It occupies a volume of . The gas is compressed slowly, so that the temperature does not change. Calculate the new volume when the pressure is .
