With reference to Joules apparatus inFigure2.6, assuminga massof 100.Kg ofwater about100L,a weight witha massof 20.0kg, anda dropof 2.00meters,calculate howmany drops it wouldtake toraise the temperature of the water by1.00C. The acceleration dueto gravityis 9.81m/s2.Hint: See Example2.5.
During a recent winter month in Sheboygan, Wisconsin, it was necessary to obtain 3500 kWh of heat provided by a natural gas furnace with 89% efficiency to keep a small house warm (the efficiency of a gas furnace is the percent of the heat produced by combustion that is transferred into the house). (a) Assume that natural gas is pure methane and determine the volume of natural gas in cubic feet that was required to heat the house. The average temperature of the natural gas was 56 F; at this temperature and a pressure of 1 atm, natural gas has a density of 0.68 1 g/L. (b) How many gallons of LPG (liquefied petroleum gas) would be required to replace the natural gas used? Assume the LPG is liquid propane [ C3H8 : density, 0.5318 g/mL; enthalpy of combustion, 2219 Id/mo for the formation of CO2(g) and H2O(l) ] and the furnace used to burn the LPG has the same efficiency as the gas furnace. (c) What mass of carbon dioxide is produced by combustion of the methane used to heat the house? (d) What mass of water is produced by combustion of the methane used to heat the house? (e) What volume of air is required to provide the oxygen for the combustion of the methane used to heat the house? Air contains 23% oxygen by mass. The average density of air during the month was 1.22 g/L. (f) How many kilowatt—hours ( 1kWh=3.6106 J) of electricity would be required to provide the heat necessary to heat the house? Note electricity is 100% efficient in producing heat inside a house. (g) Although electricity is 100% efficient in producing heat inside a house, production and distribution of electricity is not 100% efficient. The efficiency of production and distribution of electricity produced in a coal-fired power plant is about 40%. A certain type of coal provides 2.26 kWh per pound upon combustion. What mass of this coal in kilograms will be required to produce the electrical energy necessary to heat the house if the efficiency of generation and distribution is 40%?
The label on a pressurized can of spray disinfectant warns against heating the can above 130 F. What are the corresponding temperatures on the Celsius and kelvin temperature scales?
Ethylene glycol is the main component in automobile anti-freeze. To monitor the temperature of an auto cooling system, you intend to use a meter that reads from 0 to 100. You devise a new temperature scale based on the approximate melting and boiling points of a typical antifreeze solution (45C and 115C). You wish these points to correspond to 0A and 100A, respectively. a. Derive an expression for converting between A and C. b. Derive an expression for converting between F and A. c. At what temperature would your thermometer and a Celsius thermometer give the same numerical reading? d. Your thermometer reads 86A. What is the temperature in C and in F? e. What is a temperature of 45C in A?
At what point is the temperature in F exactly twice that in C?
Finding the volume of a flask. A student obtained a clean, dry glass-stoppered flask. She weighed the flask and stopper on an analytical balance and found the total mass to be 34.166g. She then filled the flask with water and obtained a mass for the full stoppered flask of 68.090g. From these data, and the fact that at the temperature of the laboratory the density of water was 0.9975g/mL, find the volume of the stoppered flask. a. First we need to obtain the mass of the water in the flask. This is found by recognizing that the mass of a sample is equal to the sum of the masses of its parts. For the filled, stoppered flask: Massoffilledstopperedflask=massofemptystopperedflask+massofwater,somassofwater=massoffilledflaskmassofemptyflask Massofwater=gg=g Many mass and volume measurements in chemistry are made by the method used in la. This method is called measuring by difference, and is a very useful one. b. The density of a pure substance is equal to its mass divided by its volume: Density=massvolume or volume=massdensity The volume of the flask is equal to the volume of the water it contains. Since we know the mass and density of the water, we can find its volume and that of the flask. Make the necessary calculation. Volumeofwater=volumeofflask=mL
