GCSE Edexcel Physics Volume and Pressure in Gases: Three states of matter are solid

Question

Three states of matter are solid, liquid and gas.

(i) Particles in each state of matter move in different ways.

Draw a line from each state of matter to the description of the way in which the particles move.

State of matter
Particles

solid
move randomly and are close together

liquid
do not move

gas
move around quickly and are far apart

vibrate about fixed positions

(ii) Complete the sentence by putting a cross (X) in the box next to your answer.

When a gas is cooled most of the particles

A become heavier
B become lighter
C move faster
D move slower

(b) The volume of dry air in a sealed balloon can be changed by cooling the balloon.

The temperature of the air in the balloon is 20 °C.

(i) Complete the sentence by putting an (X) in the box next to your answer.

When 20 °C is changed to kelvin it becomes

A 253 K
B 273 K
C 293 K
D 373 K

(ii) At this temperature, the volume of air in the balloon is 0.25 m³.
When the balloon is cooled the volume becomes 0.10 m³.
Assume that there is no change in pressure.

Calculate the new temperature of the air in the balloon in kelvin.
Use the equation T₂ = V₂T₁ / V₁.

temperature of the air in the balloon = ............. K

(iii) Suggest one way of increasing the volume of the balloon.
