A thermоmeter hаs а mаss оf 31 g, specific heat capacity оf 815 J/kg oC, and an initial temperature of 20o C. It is immersed in 119 g of water. A 250 g piece of copper at 125oC is dropped into the water. The final temperature of the water, copper, and thermometer is 75o C. What is the initial temperature of the water before insertion of the thermometer and copper? Tiw = oC
