The resistance r of a piece of wire has thermometric properties which can be described as a linear function of temperature (t), see below: where a and b are constants. the resistance of the wire is found to be 3.3 2 at the temperature of melting ice (0 °c) and 8.5 2 at the boiling of water (100 °c) at atmospheric pressure. [15 marks] a, find a and b b. determine the temperature when r is 6.9 2
