) The volume, Vm^3 of a fixed mass of gas is inversely proportional to the pressure, P pascals, When V=2.5,P=240 (a) Find the volume when the pressure is 180 pascals. (b) Find the pressure when the volume is 3.5m^3

**(a)**Since the volume and pressure are inversely proportional, we can write their relationship as:V * P = k (where k is a constant)We can find the value of k using the given values:2.5 * 240 = k k = 600Now, we can find the volume when the pressure is 180 pascals:V * 180 = 600V = 600 / 180V = **3.33 m³****(b)**Using the same relationship, we can find the pressure when the volume is 3.5 m³:3.5 * P = 600P = 600 / 3.5P = **171.43 pascals**
