- The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0C and 101 kPa. The volume of the balloon is 400 m3. To what temperature must the air in the balloon be warmed before the balloon will lift off? (Air density at 10.0C is 1.244 kg/m3.)arrow_forwardOne easy way to reduce heating (and cooling) costs is to add extra insulation in the attic of a house. Suppose the 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, then by what percentage would the heating cost of the house drop? Take the single story house to be of dimensions 10 m by 15 m by 3.0 m. Ignore air infiltration and heat loss through windows and doors.arrow_forwardYou are planning a birthday party for your niece and need to make at least 4 gallons of Kool-Aid, which you would like to cool down to 32 oF (0 °C) before the party begins. Unfortunately, your refrigerator is already so full of treats that you know there will be no room for the Kool-Aid. So, with a sudden flash of insight, you decide to start with 4 gallons (1 gallon = 3.7854 liters, and a liter (L) is 0.001 cubic meters) of the coldest tap water you can get, which you determine is 50 °F (10 °C), and then cool it down with a 1- quart (1/4 of a gallon) chunk of ice you already have in your freezer. The owner's manual for your refrigerator states that when the freezer setting is on high, the temperature is -20 °C. Will your plan work? You assume that the density of the Kool-Aid is about the same as the density of water. You look in your physics book and find that the density of water is 1.0 g/cm3 (1kg/L), the density of ice is 0.9 g/cm3 (0.9kg/L), the heat capacity of water is 4200 J /…arrow_forward
- To help prevent frost damage, 4.77 kg of 0°C water is sprayed onto a fruit tree. The latent heat of fusion of water is 79.8 kcal/kg. (a) How much heat will be released by the water as it freezes?(b) How much would the temperature of the 260-kg tree decrease if it lost this amount of heat, given its specific heat is 0.800 kcal/(kg · °C), and no phase change occurs?arrow_forwardAssume that you are evaluating a building that has a heated slab-on-grade floor with edge insulation of R = 5.0 and a perimeter of 1000 ft. If your design temperature range is 5°F to -5°F, what is the heat loss, in BTU/hr, through the edge of the floor? 62,000 BTU/hr 31,000 BTU/hr 47,000 BTU/hr 23,000 BTU/hrarrow_forwardNative Canadians used to boil water from maple tree sap by heating rocks and placing them into vats of sap sitting in hollowed-out tree logs. For this problem, assume that the syrup and the rocks have the heat capacities of water and sand respectively.

- On a cold day, you grab a piece of metal and a fallen tree limb, both with bare hands. Both have been lying outside for a long time and are at the same temperature. The metal feels colder than the tree limb. Why?arrow_forwardA tank of water has been outdoors in cold weather, and a slab of ice 5.3 cm thick has formed on its surface (see the figure). The air above the ice is at -6.0°C. Calculate the rate of formation of ice (in centimeters per hour) on the ice slab. Take the thermal conductivity of ice to be 0.0040 cal/s-cm-C°, its density to be 0.92 g/cm?, and its latent heat of fusion to be 333 kJ/kg. Assume no energy transfer through the tank walls or bottom.

In the desert climate of Phoenix, Arizona, however, temperatures rise above that almost every day in July and August. Explain how the evaporation of water helps limit high temperatures in humid climates.arrow_forwardA 14500 kg tractor trailer travels up and down a 75-meter hill on its way to pick up a load oflumber weighing 26000 kg. it then turns around and makes the trip back along the same route.Upon descending the hill in either direction the brakes absorb 20% of the truck’s energy.
