​a) State the law that relates the volume of a gas to the temperature of a gas.
b) Fig 7. shows an experiment set-up that may be used to investigate one of the laws. The glass tube has a uniform bore and it is graduated in millimeter
​i) Describe how the experiment was carried out and explain how the results obtained verify the law.
ii) Limitations of the set up are? c) In an experiment to find the relation between pressure, p, and temperature, of a gas at a constant volume, values of temperature were determined. The results obtained are shown in the graph below.
​(i) From the graph, determine the pressure at a temperature of 273K.
(ii) Assuming the relation p/T0+0 = constant holds for this graph determine the value of the constant T0 K.C.S.E Physics Q & A - MODEL 2002PP2QN05
a) Fig 6.1 shows the cross- section of a ripple tank full of water. A piece of cork floats on the surface of the water as shown. Fig 6 II shows the water surface viewed from above. A straight edge vibrator placed at the end A of ripple tank generates water waves, which travel towards end B as shown.
(i) Identify the type of waves generated on the water surface.
