Judy places 195 g of boiling water in a thermos bottle. How many grams of ice at -11.4°C must Judy add to the thermos so that the equilibrium temperature of the water is 79.1°C? The specific heat capacity of: (a) water is 4190 J/(kg-K) and (b) ice is 2100 J/(kg-K); for water, the latent heat of fusion is 3.34xx10 J/kg and the latent heat of vaporization is 2.256x10³ J J/kg.

A high-end gas stove usually has at least one burner rated at 14 000 Btu/h. (a) If you place a 0.25-kg aluminum pot containing 2.0 liters of water at 20.C on this burner, how long will it take to bring the water to a boil, assuming all the heat from the burner goes into the pot?

At temperatures of a few hundred kelvins the specific heat capacity of copper approximately follows the empirical formula c=a+T+T2, where a=349J/kgK, =0.107J/kgK2, and =4.58105JkgK. How much heat is needed to raise the temperature of a 2.00-kg piece of copper from 20 to 250 ?
What are the main methods of heat transfer front the hot core of Earth to its surface? From Earth's surface to outer space? When our bodies get too warm, they respond by sweating and increasing blood circulation to the surface to transfer thermal energy away from the care. What effect will this have on a person in at 40.0C hot tub? Figure 14.30 shows a cutaway drawing of a thermos battle (also known as a Dewar flask), which is a device designed specifically to slow down all terms at heat transfer. Explain the functions of the various parts, such as the vacuum, the silvering of the walls, the thin-walled long glass neck, the rubber support, the air layer, and the stopper. Figure 14.30 The construction of a thermos bottle is designed to inhibit all methods of heat transfer.

A 30.0-g ice cube at its melting point is dropped into an aluminum calorimeter of mass 100.0 g in equilibrium at 24.0 with 300.0 g of an unknown liquid. The final temperature is 4.0 . What is the heat capacity of the liquid?
A construction worker uses a steel tape to measure the length of an aluminum support column. If the measured length is 18.700 m when the temperature is 21.2C, what is the measured length when the temperature rises to 29.4C? Note: Dont neglect the expansion of the tape.
One easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose a single-story cubical house already had 15 cm of fiberglass insulation in the attic and in all the exterior surfaces. If you added an extra 8.0 cm of fiberglass to the attic, by what percentage would the heating cost of the house drop? Take the house to have dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors, and assume that the interior is uniformly at one temperature and the exterior is uniformly at another.
Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per nub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warned is only 0.100 kg, mostly in the palms and fingers.
