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.
