ABSTRACT

Changes that occur at constant temperature are called isothermal changes. When a fixed mass of gas at constant temperature changes from pressure p1 and volume V1 to pressure p2 and volume V1 then:

Problem 1. A gas occupies a volume of 0.10 m3 at a pressure of 1.8 MPa. Determine (a) the pressure if the volume is changed to 0.06 m3at constant temperature, and (b) the volume if the pressure is changed to 2.4 MPa at constant temperature.
