K.C.S.E Physics Q & A - MODEL 2003PP2QN06
​a) Figure 6 shows a simple set up for pressure law apparatus.
​Describe how the apparatus may be used to verify pressure law. Initial reading of pressure and temperatures are recorded.
b) The graph in fig 7 shows the relationship between the pressure and temperature for a fixed mass of an ideal gas at a constant volume.
​(i) Given that the relationship between pressure, p, and temperature, T n Kelvin is of the form P = kT+ C where k and C are constants, determine from the graph, values of k and c.
(ii) Why would it be impossible for pressure of the gas to reduced to zero in practice? (c) A gas is put into a container of fixed volume at a pressure of 2.1 x 105 N/m2 and temperature 27C. the gas is then heated temperature of 327C. Determine the new pressure.
