Question

A sample of gas has a volume of 2.4 L and a pressure of 1.2 atm. What would the pressure of the same gas sample be if the volume is reduced to 1.8 L at a constant pressure?

Answer 1

`"New volume "=` `1.6*L`

Explanation:

`P_1V_1=P_2V_2`, amount of gas, and temperature constant.

`P_2=(P_1V_1)/V_2` `=` `(1.2*atmxx2.4*L)/(1.8*L)`

The smaller volume is reasonable, inasmuch as the pressure was INCREASED.
