i need help with this question in details, many thanks

Problem 2: Some of the most common sources of heat in a chemical plant are hot water and steam. The following questions explore the value of these as potential heat sources: a/ Suppose that a hot water stream at 225C is available as a heating source at a flow rate of 8.5 kg/s. How much heat can be extracted from this stream if it is cooled to 150C? The heat capacity of water at these temperatures is approximately 4.5 kJ/kg K. b/ Suppose that saturated steam at 238.5C is available as a heating source at a flow rate of 8.5 kg/s. How much heat can be extracted by condensing the steam to liquid water at the same temperature? c/ Based on your answers from parts (a) and (b), which of the above (hot water or steam) would you recommend as a source of heat?
