K.C.S.E Physics Q & A - MODEL 2015PP1QN17
(a) Figure 11 shows a graph of pressure (p) against volume (y) for a fixed mass of a gas at constant temperature
In the space provided, sketch the corresponding graph of p against 1/v.
(b) Explain the pressure law using the kinetic theory of gases.
(c) 20 cm3 of a gas exerts a pressure of 760 mmHg at 25°C. Determine the temperature of the gas when the pressure increases to 900 mmHg and the volume reduces to 15 cm3.
(d) Figure 12 shows the path of a light ball projected horizontally.
The ball is then made to spin in an anticlockwise direction as it moves:
(i) on the same axis, sketch the new path of the ball.
(ii) explain how the ball attains the new path
