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.

#19Problem: Let's determine the initial temperature of copper.
A copper cube with a mass of 85 grams is heated in a boiling water bath to a high temp. The cube is removed from the bath and placed on a large block of ice in an isolated container. The ice has a mass of 145 grams and is at a temperature of -12 Celsius. The ice is melted by the heat exchange, assume equilibrium is 0 Celsius.
C ice: 2090 J/Kg C
C copper: 390 J/kg C
Latent heat for melting Ice= 333kJ/kg
Explain in 3 paragraphs.
How would you know when an ice sample is already at 0ºC without using a thermometer?

- A 5000 kg African elephant has a resting metabolic rate of 2500 W. On a hot day, the elephant’s environment is likely to be nearly the same temperature as the animal itself, so cooling by radiation is not effective. The only plausible way to keep cool is by evaporation, and elephants spray water on their body to accomplish this. If this is the only possible means of cooling, how many kilograms of water per hour must be evaporated from an elephant’s skin to keep it at a constant temperature?arrow_forwardA brass boiler has a base area of 0.15 m2 and thickness 1.0 cm.
