1.)An aluminum tank with a volume of 1000 liters is filled with gasoline. Both are at a temperature of 12°C. The tank is transported to a place where the temperature is 37° and, due to the difference between the volumetric expansion coefficients of the metal and the liquid, the ebb of the tank. Assuming the tank expands like a massive volume of aluminum, how many liters of gasoline overflow from the tank? Data: βaluminum=7*10-5/ºC and βgas=9.5*10-4/ºC

A body is removed from a confined space where the temperature is 70°C and is taken outside, where the air temperature is 10°C. After one-half minute, the body's temperature is read as 50°C. How long will it take for the body's temperature to reach 15°C? What is the value of the proportionality constant?

The temperature at the surface of the bottom of the tank is 75°F rises to the surface where the temperature is 85°F. What is the percent inccrease in volume of the bubble if the height of water in the tank is 30ft and the atmospheric pressure is 14.7 psia
Calorimetry In a kitchen there are two identical pans that have been previously heated, one of the pans is filled with 1/2 liter of Water at 100◦C and the other with 1/2 liter of oil at 130◦C. After that, no there is more fire that keeps introducing heat to both liquids. In that instant, a person who had cut 300 grams of potato into small cubes at a temperature of 25◦C, decides to pour half the amount of potato in the boiling water and the other half in the burning oil. a) Determine the temperature of the thermal equilibrium between the pore potatoes in the water, and the same for nocao in the oil, considering each cases as isolated systems. (b) Explain why the thermal equilibrium temperatures in both cases are almost the same, mention the physical fundamentals that characterize that result. information in the image respectively: water density: oil density: specific heat of water: specific oil heat: specific heat of the potato:
In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
Unreasonable Results - A slightly deranged Arctic inventor surrounded by ice thinks it would be much less mechanically complex to cool a car engine by melting ice on it than by having a water-cooled system with a radiator, water pump, antifreeze, and so on. (a) If 80% of the energy in 1.00 gal of gasoline is converted into “waste heat” in a car engine, how many kilograms of 0C ice could it melt? (b) Is this a reasonable amount of ice to carry around to cool the engine for 1.00 gal of gasoline consumption? (c) What premises or assumptions are unreasonable?
Assume the following: ●In a light water reactor, approximately 1.0kg of spent nuclear fuel is produced for every50. megawatt-days (MWd) of thermal energy input. ●For the purposes of this analysis, assume the spent nuclear fuel produced is 1.8% Pu-240by mass. Pu-240 has a half-life of 6,430 years. ●The thermal efficiency of the power plant is 38% ●Use equation for radioactive decay: Qt= Q0^e-kt where: ○Qt = quantity of radioactive material at time t ○Q0 = original quantity of radioactive material ○k = the decay constant ○t = time interval in years ○The decay constant k is defined by the relation: Half life = ln(2)/k Diablo Canyon stores 95% of its spent nuclear fuel onsite. ii) How many metric tons of Pu-240 in the spent fuel will still be onsite in that year?

A dormitory room measures 4m x 6m x 6m. A student turns on a 150 watts fan before leaving the room on a summer day, hoping that the room will be cooler when she returns in the evening. Assume that all doors and windows are tightly closed, and there is no heat transfer through the walls and windows. At the start of the day, the room temperature is 15°C, and the pressure is 100 kPa. What will be the temperature inside the room when the student returns 10 hours later, given the specific heat value of air at room temperature?
Saponification is a process wherein soap is added to a certain type of oil to produce grease. One such grease is said to have 75.7 % by volume oil and 24.3% by volume soap, wherein the oil and soap have densities 760 kgm/m3 and 6,250 kgm/m3, respectively. This kind of grease is sold by packs shaped like a sphere with a diameter of 20 cm for convenience. Calculate: a) the mass of oil per pack (kgm), b) the mass of soap per pack (kgm), c) the weight of each pack (kgf), d) the specific weight of grease (N/m3), e) will the grease float if it is placed in water whose density is 1000 kgm/m3?
