6 This questiоn is аbоut gаs pressure. (а) The diagram shоws a cylinder containing propane gas. Refer to addendum Figure 6.1 The propane gas is stored in the cylinder at a pressure of 1.03 × 106 Pa. (i) State the formula linking pressure, force and area. (1) (ii) The cylinder has an internal surface area of 1.13 m2. Calculate the force exerted on the walls of the cylinder by the propane gas. (3) (iii) Explain why the pressure exerted by the propane gas acts equally in all directions. (2) (b) The graph shows how the pressure of a gas varies with its temperature. Refer to addendum Figure 6.2 (i) Describe how the graph can be used to show that there is a minimum value of temperature, known as absolute zero. (2) (ii) Give the value of absolute zero in °C. (1) (iii) Temperature can also be measured in kelvin. Copy the axes and sketch a graph to show how the pressure of a gas varies with its kelvin temperature. (2) Refer to addendum Figure 6.3 (c) The pressure in the cylinder is at a pressure of 1.03 × 106 Pa when the temperature is 20 °C. Calculate the change in pressure inside the gas cylinder when the temperature increases to 30 °C. (3) (Total for question 6 = 14 marks)
