A piston in an airtight pump is withdrawn so that the volume of the air chamber is increased five times. What is the change in pressure?
The change in pressure due to the given changes.
Answer to Problem 14A
The pressure is decreased by
Explanation of Solution
Given:
Volume after withdrawn is increased 5 times.
Formula used:
Boyle’s law states that at constant temperature, the product of pressure and volume of the given mass of gas is constant.
The Boyle’s law is expressed as follows:
Here,
Calculation:
Let the volume of air chamber be
So, the volume of air chamber after airtight pump is withdrawn =
Substitute
Conclusion:
Thus, the pressure is decreased by
