A glass contains 0.25 kg of lemonade (mostly water) initially at 25°C. How much ice, initially at -20 C°, must you add to obtain a final temperature of 0 C° with all the ice melted? Note: Neglect the heat capacity of the glass. (Heat capacity of ice is 2100 J/kg.K , heat of fusion for water is 334x10' J/kg)

One way to cool a gas is to let it expand. When a certain gas under a pressure of 5.00 106 Ha at 25.0C is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 106 Pa. (a) What is the initial temperature of the gas in Kelvin? (b) What is the final temperature of the system? (See Section 10.4.)
For the human body, what is the rate of heat transfer by conduction through the body’s tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is 2.00C, and the skin area is 1.50m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)
Calculate the rate of heat conduction out of the human body, assuming that the core internal temperature is 37.0 , the skin temperature is 34.0 , the thickness of the fatty tissues between the core and the skin averages 1.00 cm, and the surface area is 1.40 m2.
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? (b) Once boiling begins how much time is required to boil all the water out of the pot?
A cylinder of volume 50.0 cm3 made of Pyrex glass is full to the brim with acetone. If the cylinder and acetone are warmed by 30.0C, (a) what is the change in volume of the glass? (b) Of the acetone? (c) Will any acetone spill out of the cylinder? (See Section 10.3.)
Suppose a person is covered head to foot by wool clothing with average thickness of 2.00 cm and is transferring energy by conduction through the clothing at the rate of 50.0 W. What is the temperature difference across the clothing, given the surface area is 1.40m2 ?
A copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100.C and that of the far end of the aluminum rod is held at 0C. If the copper rod is 0.15 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50.C?
