A piece of metal with a mass of 1.8 kg, specific heat of 205 J/kg/°C, and initial tem- perature of 83°C is dropped into an insulated jar that contains liquid with a mass of 4 kg, specific heat of 1000 J/kg/°C, and initial tem- perature of 6°C. The piece of metal is removed after 2.6 s, at which time its temperature is 20°C. Find the temperature of the liquid after the metal is removed. Neglect any effects of heat transfer to the air or to the insulated jar.
