Answer:
D. pressure and volume
Step-by-step explanation:
Boyle’s law states that,
For a given amount of a gas, Pressure is inversely proportional to its volume at constant temperature
Thus the expression is
PV = constant (T and n are constant)
When there is a change in pressure and volume we make use of the expression
(T and n are constants)
Where
and
are the Initial pressure and volume and
and
are the final pressure and volume
Inversely proportional means when one increases the other one decreases. That is as per Boyle’s law when Pressure increases the volume will decrease and vice versa.
