(b) A 200 km/h Wind significant digit) the mass of the roof. Assume the roof is not nailed down. (c) A tank contains water having a volume of 1.0 m³ and initial temperature Tw= 20 °C. Calculate the mass of ice, with initial temperature Tice,in= -20 °C, that you must add to the water so that the final state is 100% ice at temperature Tfinal = 0 °C.
