A sample of oxygen with volume of `500` cc at a pressure of ` 2` atm is compressed to a volume of `400` cc. What pressure is needed to do this if the temperature is kept constant?

Text Solution

Verified by Experts

Temperature is constant ,so `P_(1) V_(1) = P_(2)V_(2) therefore P_(2) = P_(1)(V_(1))/(V_(2)) = 2[(500)/(400)] = 2.5`atm
