    Heat Transfer
    Any help will be appreciated,

    In an experiment to determine the rate at which heat is extracted from a hot material, 305 g of the material at 90 C is put into a 50 mm diameter copper vessel to a depth of 90 mm as shown below. The hot material and calorimeter are placed in a container holding 189 g of cold water at 22.7 C. The temperature of the water is then measured every 30 seconds for 3minutes. The average temperature rise per second is calculated as 0.0065 0.0005 C/sec.
    From the data provided, determine the average heat power ( in kW ) transferred to the water.
