1) Use the Energy-Interaction Model to explain whether the following statement is true or false: "A quantity of ice at 0℃ must contain less total energy than the same quantity of water at 0℃.2) According to the definition of heat in the online reading, can an energy system contain a certain amount of heat? Explain.3) Imagine that you place a piece of copper with an initial temperature of 20℃ in contact with some liquid water with an initial temperature of...

3) Imagine that you place a piece of copper with an initial temperature of 20°C in contact with some liquid water with an initial temperature of 100°C. Assume that the physical system consisting of the copper and the water is thermally isolated from everything else; i.e., they can only exchange energy with each other. a) Sketch two three-phase diagrams, one for each substance, and mark the initial state for each one. Explain in...
A piece of solid lead weighing 32.6 g at a temperature of 311 °C is placed in 326 g of liquid lead at a temperature of 367 °C. After a while, the solid melts and a completely liquid sample remains. Calculate the temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings. The enthalpy of fusion of solid lead is ΔHfus = 4.77 kJ/mol at its melting point of 328 °C, and the molar heat capacities for...
A 0.220-kg piece of aluminum that has a temperature of -191 °C is added to 1.5 kg of water that has a temperature of 2.4 °C. At equilibrium the temperature is 0 °C. Ignoring the container and assuming that the heat exchanged with the surroundings is negligible, determine the mass of water that has been frozen into ice.
A piece of solid lead weighing 34.2 g at a temperature of 315 °C is placed in 342 g of liquid lead at a temperature of 376 °C. After a while, the solid melts and a completely liquid sample remains. Calculate the temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings. The enthalpy of fusion of solid lead is ΔHfus = 4.77 kJ/mol at its melting point of 328 °C, and the molar heat capacities for...
