PV = k, where Pis pressure, Vis volume, and k is a constant

Question 1

Suppose you have a gas in a container being pressed down by a piston. The initial volume of the gas is 5.0 m3 and

the pressure is 7.5 mmHg. If the volume decreases to 4.0 m, what is the pressure? (The product of the volume and

pressure remain constant.)

(5.0 m)(7.5 mmHg) = (P)(4.0 m)
