The Particle Model
Question 1 of 6
This question is about the different states of matter.
The table shows some physical changes.
Complete the table by giving the state of the substances before and after each change.
The melting point of bromine is −7 °C.
The boiling point of bromine is 59 °C.
What state is bromine at room temperature?
What is the best description of the particles in a liquid?
The particle model can be used to explain the physical properties of solids, liquids and gases.
What is meant by 'physical property'?
The diagram shows the arrangement of particles in the three states of matter.
Each circle represents a particle.
Use the letters X, Y and Z to give the starting and finishing states of matter for each of the changes in the table below.
Which word describes water changing from a liquid to a solid?
Which of these changes takes place when solid iodine is heated to form iodine gas?
The table below shows the melting and boiling points of four substances, A, B, C and D.
Give the letter of a substance that is a solid at 20°C.
Give the letter of a substance that is a liquid at 40°C.
Particles in a solid are closely packed, arranged in a regular pattern and vibrate about fixed positions.
Describe the arrangement and movement of the particles in a gas.
There are three states of matter: solid; liquid and gas.
They have different properties, which can be explained by looking at the arrangement of their particles.
What type of change is a change of state?
Which two statements are correct about the particles when a liquid turns into a gas?
What is the name of the process that occurs when a substance changes from a gas to a liquid?
This question is about changes of state.
The image below shows how the temperature of water changed with time as a student heated it from ice to steam.
Name the changes of state represented by letters X and Y in the image above.
Explain what is happening to the substance in the sections A-B and B-C of the graph.
Give the boiling point and melting point of water.
This question is about the particle model.
The model is used to explain the physical properties of solids, liquids and gases.
The image below shows a simple model of the three states of matter.
Which states of matter are represented by A, B and C?
Give the state symbols for the states of matter represented by A, B and C.
Describe the difference between the solid and gas states, in terms of the arrangement and movement of their particles.
Use the model in the figure above in your answer.
There are limitations to the particle model.
Give two limitations of the particle model in the image above.
