When a casserole was removed from an oven at 6p .m., its temperature was 150°C. Its' temperature had fallen to 70°C by 6.20 p.m. The casserole can be…eaten when its temperature has reached 30°C.i) Estimate when this will be by assuming a constant rate of cooling from 150°C.ii) An improved model of the casserole's temperature, B deg * C at time 1 minutes after 6 p.m., can be deduced from the assumptions that:the rate of loss of temperature is proportional to the difference in temperature between the casserole and the kitchen;(Newtons Law of routing)the kitchen remains at a constant 20°C.Show that these assumptions lead to an equation of the form t = a * ln(theta - 20) + b where a and bare constants.Find a and b, and hence obtain a new estimate for the time at which the casserole can be put into the freezer.
