Some hot water that has a mass of 750 g and a temperature of 75°C is poured over 1,500 g of an unknown substance that has a temperature of 15°C. The temperatures of the water and the substance are both monitored. At an instant t, the water temperature is 55°C and the substance temperature is 25°C. Find the specific heat capacity of the substance. Use a value of 4,184 J/kg.*C for the water's specific heat capacity. Assume that the water does not heat its surroundings.
