Thus, the plot of V versus P will be a rectangular hyperbola . 2. According to Boyle's law, at a constant temperature, the pressure of a fixed amount of gas varies inversely to its volume. 3. According to Boyle's law, the product of pressure and volume is constant a constant temperature. The graph of PV versus P is constant which indicates that the given gas obeys Boyle's law.

At constant temperature, the effect of change of pressure on volume of gas was as given below: Pressure in atmospheres Volume in litres 0 . 20 112 0 . 25 89 . 6 0 . 40 56 0 . 80 28 1 . 00 22 . 4 (b) Assuming that the pressure values given above are correct, find the correct measurement of the volume at 0.60 atmosphere pressure.

The correct measurement of the volume are given bellow: Pressure in atmospheres Volume in litres 0 . 20 112 0 . 25 89 . 6 0 . 40 56 0 . 80 28 1 . 00 22 . 4 At constant temperature, the effect of change of pressure and volume of a gas given below here it is given that and volume is given that during the pressure value given above are correct find the correct measurement of the above at 0 . 6 atmospheric pressure here it is 0 . 4 atmospheric pressure volume is given 0 . 80 atmospheric pressure volume is given that but here we find the volume at 0 . 60 at here we want to the find volume here: As PV= 22.4 constant At P= 0.6 Volume (V)= 22 . 4 0 . 6 = 37 . 4 Volume is 37 . 4 litres at P = 0 . 6
