An insulated container, made of copper, has a mass of 0.120 kg. The container is filled with 0.150 kg of water and 0.0220 kg of ice in thermal equilibrium at 0°C. A 0.750 kg lead block that has been heated to Ti is dropped into the insulated container and the system comes to a final equilibrium temperature of 25.6°C. What was the initial temperature, Ti, of the lead block? Assume that no heat is lost to the surroundings.

A piece of copper, mCu = 4.80 kg, at an initial temperature of T °C is placed with 2.00 kg of ice that is initially at —20.0°C .The ice and copper are in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is 1.20 kg of ice and 0.800 kg of liquid water in the container. What was the initial temperature of copper? (cice = 2220 J/kg.K ; cCu = 386 J/kg.K )

A 6.00 kg piece of solid copper metal at an initial temperature T is placed with 2.00 kg of ice that is initially at -30.0 ∘C. The ice is in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is 0.80 kg of ice and 1.20 kg of liquid water. What was the initial temperature of the piece of copper?

A $6.30 \mathrm{~kg}$ piece of solid copper metal at an initial temperature $T$ is placed with $2.00 \mathrm{~kg}$ of ice that is initially at $-27.0^{\circ} \mathrm{C}$. The ice is in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is $0.80 \mathrm{~kg}$ of ice and $1.20 \mathrm{~kg}$ of liquid water. What was the initial temperature of the piece of copper?
