The temperature 0°C measured at a distance x cm from a candle flame is given by 0 = 20 + 400 3 22 for distances > 1 a) find the temperature gradient (i.e. the rate at which the temperature decreases with distance) 8 cm from the flame b) Find the rate of change of temperature gradient with respect to distance, 4 cm from the flame. Give your answers to 1 decimal place (1dp). -1 °C cm (to 1dp) temperature gradient = rate of change of the temperature gradient = °C cm² (to 1dp)
