A 1.19-kg sample of water at 13°C is in a calorimeter. You drop a piece of steel with a mass of 0.31 kg at 224°C into it. After the sizzling subsides, what is the final equilibrium temperature? Make the reasonable assumptions that any steam produced condenses into liquid water during the process of equilibration and that the evaporation and condensation taken together don't affect the outcome, as we'll see later.
Hint
The final equilibrium temperature of water and steel is °C.
If the water is in a glass beaker with a mass of 0.2 kg, which in turn is in a calorimeter, with the beaker at the same temperature as the water, how will this affect the answer? Try answering before doing a detailed calculation.

A 75-kg block of ice at -13°C is placed in an oven set to a temperature of 105°C. The ice eventually vaporizes and the system reaches equilibrium.
How much energy, in joules, is needed to vaporize all the water at 100°C?
How much energy, in joules, is required to heat the resulting steam from 100°C to 105°C?
What is the total energy, in joules, that is needed to heat the block of ice from its initial temperature to water vapor at its final temperature?
A frictionless piston–cylinder device contains 10 lbm of steam at 60 psia and 320°F. Heat is now transferred to the steam until the temperature reaches 400°F. If the piston is not attached to a shaft and its mass is constant, determine the work done by the steam during this process.
