(a) The graph between V and T is a …………… .

(b) Check whether the line passes through the origin.

(c) Which law is obeyed.

800 cm³ of gas is collected at 654 mm pressure. At what pressure would the volume of the gas reduce by 40% of its original volume, temperature remaining constant?

At constant temperature, the effect of change of pressure on volume of a gas was as given below :

(a) Plot the following graphs :

(i) P vs V

(ii) P vs 1/V

(iii) PV vs P

(b) Assuming that the pressure values given above are correct, find the correct measurement of the volume at 2.3 atmosphere pressure.
