Question

The volume of gas with some marble is 250 ml at pressure of 640 torr.The volume becomes 200 ml at 900 mm of Hg pressure. Calculate the volume occupied by marble

Answer 1

Answer:

Step-by-step explanation:

Given:

Initial pressure of the gas, P1 = 760 mm Hg

Initial volume of the gas, V1 = 100 ml

Final pressure of the gas, P2 = 1000 mm Hg

New volume after the pressure change, V' = 80 ml

To Find:

The volume occupied by the marble pieces.

Calculation:

- For the gas, at constant temperature, we have:

P1V1 = P2V2

⇒ 760 × 100 = 1000 × V2

⇒ V2 = 76 ml

- The Volume of marble pieces = V'- V2

⇒ V = 80 - 76

⇒ V = 4 ml

- So, the volume occupied by the marble pieces is 4 ml.
