Question: 2 the variation in the density of water p with...

Question details

(2) The variation in the density of water, p with temperature, T, in the range 20 CS in the following table. Ts 50 °C, is given Temperature C) 20 | Density (kg/m) | 998.2 | 997. i | 995.7- 994.1一 一992.2 ー990.2 988.1 25 30 35 40 45 50 Use these data to determine an empirical equation of the form氏7) = cl + C1T+CT which can be used to predict the density over the range indicated. Compare the predicted values with the data given by plotting them together (no hand drawing). Explain how you find the value of ci, c2 and cs. What is the density of water at 42.1°C? What is the density of water at 4°C? Is your prediction for 4 °C close to 1000 kg/m3? (10 pt)
