End of topic quiz
Topic P1: Matter
Instructions and answers for teachers
These instructions cover the learner activity section which can be found on page 16. This
end of topic quiz supports OCR GCSE (9–1) Physics A (J249), Topic P1.
When distributing the activity section to the learners either as a printed copy or as a
Word file you will need to remove the teacher instructions section.
The Activity
This lesson element is a teaching and learning resource comprised of 40 marks covering a
range of question types. The quiz starts with some multiple choice questions (MCQs) and
them moves on to some short answer questions and then finally on to some longer answer
questions.
This resource can be used to test and consolidate understanding at the end of teaching the
topic or to revisit and refresh knowledge at a later point in the course.
Learning Outcomes
This lesson element relates to the specification learning outcomes in Topic P1: Matter. The
questions in this quiz cover a range of the following topics:
P1.1a describe how and why the atomic model has changed over time
P1.1b describe the atom as a positively charged nucleus surrounded by negatively charged
electrons, with the nuclear radius much smaller than that of the atom and with almost all of
the mass in the nucleus
P1.1c recall the typical size (order of magnitude) of atoms and small molecules
P1.1d define density
P1.1e explain the differences in density between the different states of matter in terms of the
arrangements of the atoms and molecules
P1.1f apply the relationship between density, mass and volume to changes where mass is
conserved (M1a, M1b, M1c, M3c)
.

P1.2a describe how mass is conserved when substances melt, freeze, evaporate, condense
or sublimate
P1.2b describe that these physical changes differ from chemical changes because the
material recovers its original properties if the change is reversed
P1.2c describe how heating a system will change the energy stored within the system and
raise its temperature or produce changes of state
P1.2d define the term specific heat capacity and distinguish between it and the term specific
latent heat
P1.2e apply the relationship between change in internal energy of a material and its mass,
specific heat capacity and temperature change to calculate the energy change involved
(M1a, M3c, M3d)
P1.2f apply the relationship between specific latent heat and mass to calculate the energy
change involved in a change of state (M1a, M3c, M3d)
P1.3a explain how the motion of the molecules in a gas is related both to its temperature and
its pressure
P1.3b Explain the relationship between the temperature of a gas and its pressure at constant
volume (qualitative only)
P1.3c recall that gases can be compressed or expanded by pressure changes and that the
pressure produces a net force at right angles to any surface
P1.3d explain how increasing the volume in which a gas is contained, at constant
temperature can lead to a decrease in pressure
P1.3e explain how doing work on a gas can increase its temperature
P1.3f describe a simple model of the Earth’s atmosphere and of atmospheric pressure
P1.3g explain why atmospheric pressure varies with height above the surface of the planet
P1.3h describe the factors which influence floating and sinking
P1.3i explain why pressure in a liquid varies with depth and density and how this
leads to an upwards force on a partially submerged object describe a simple model of
the Earth’s atmosphere and of atmospheric pressure
P1.3j calculate the differences in pressure at different depths in a liquid (M1c, M3c).

Height = 0.175 m (1)
Pressure = 0.175 x 1000 x 10

Height = 0.2 m (1)
Pressure = 0.2 x 1000 x 10
= 2000 Pa (1)
There is a difference in
pressure between the top
and bottom of the object (1)
This causes an upwards
force, which matches the

(a)
(i)
Answer
Marks
As the temperature of the water
increases (1)
Max 5
Guidance
Heat energy is transferred to the
gas molecules in the form of
Kinetic Energy (1)
They therefore move faster (1)
The time between their
collisions with the glass jar
decreases (1)
Thus the force applied to the
glass jar increases as does the
pressure (1)
(ii)
Distance between walls is now
twice as large (1)
4
So collisions happen half as
often (1)
Causing the force to halve (1)
And therefore the pressure to
halve (1)
