Question

The pressure of a gas in a cylinder with a movable piston is increased from 45 kPa to 90 kPa. If the
temperature is held constant, and the initial volume of the gas in the cylinder is 0.5 m3, what is the final
volume of the gas?

a. 2 m3
b. 1 m3
c. 0.5 m3
d. 0.25 m3

Answer 1

I think these are chem questions.

Answer 2

PV=PV and rearrange to PV/P=(45KPa)(0.5m3)/(90KPa)=V. A rough estimation seesm to indicate answer choice D.
