Question 1
Paper Ref: 0620/21_Winter_2023_Q1

A gas is placed in a sealed container. The gas has a pressure of one atmosphere and a
temperature of 50°C.
It is heated to 100°C.
Which row describes the cause of the pressure of the gas and the effect of increasing the
temperature of the gas?
cause of aas pressure the effect of increased
gas Pp temperature of the gas
collisions between collisions become
gas particles less frequent
collisions between the average speed of
gas particles the gas particles increases
collisions between gas collisions become
particles and the container less frequent
collisions between gas the average speed of
particles and the container the gas particles increases

Options:
A
B
C
D
Correct Key: D
