JAMB 2020 - Question 10
Physics 2020 JAMB Past Questions - Question 10: A gas at a volume of V0 in a container at pressure P0 is compressed to one-fifth of its volume. What will be its pressure if the magnitude of its original temperature T is constant?
Choose the correct answers from the options given.
A:
B:
C:
D:
Correct Answer
D
Explanation
At constant T, P1 V1 = P2 V2.
Let P1 = P0 and V1 = V0, then solve accordingly.As pressure is varies inversely as volume according to:
Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to decrease as the volume of the container increases.
As volume is reduced by one-fifth; pressure will increase by five times.
