Answer #1

Given that:

Mass of copper = 1.05 kg

Initial temperature of copper = 100°C

Mass of water = 3.50 L = 3.5 kg

    Initial temperature of water =  0.0°C.

Specific heat of copper = 385 J/kg°C

   Specific heat of water = 4200 J/kg°C

An insulated aluminum calorimeter vessel of 150 g mass contains 300 g of liquid nitrogen boiling at 77 K. A metal block at an initial temperature of 303 K is dropped into the liquid nitrogen. It boils away 15.8 g of nitrogen in reaching thermal equilibrium. The block is then withdrawn from the nitrogen and quickly transferred to a second insulated copper calorimeter vessel of 200 g mass containing 500 g of water at 30.1 degrees celsius. The block coolds...

An 890-g iron block is heated to 370 ∘C and placed in an insulated container (of negligible heat capacity) containing 35.0 g of water at 20.0 ∘C. What is the equilibrium temperature of this system? The average specific heat of iron over this temperature range is 560 J/(kg⋅K). Answer in ∘C. I have already tried 109 ∘C and 110 ∘C, so I don't know what I'm doing wrong. :(
