Question

What would be the new pressure if 250cm3 of gas at standard pressure is compressed to a volume of 150 cm3

Answer 1

Answer:

5/3 or 1 2/3 atmospheres.

Explanation:

If the temperature is kept constant then P*V will be constant.

The standard pressure is 1 Atm. so:

250 * 1 = 150 * V

V = 250 / 150

= 5/3 Atm.
