The variation in the density of water, P. with temperature, , in the range of 20 °C<=T<=50 °C, is given in the following table. Use these data to determine an

empirical equation of the form p = C1 + C2 T + C3 T^2, which can be used to predict the density over the range indicated. Compare the predicted values with the data given. What is the density of water at 43.5 °C?
