- A Different civilization on a distant planet has developed a new temperature scale based on ethyl alcohol. The freezing point of ethyl alcohol (117C) is designated as 0J, and its boiling point (78C) is designated as 100J. Assuming that the relationship between C and J is linear, (a) draw a graph of the line using the data above. (b) what is the slope of the line? (c) what is the y-intercept of the line? (d) Write an equation to convert J to C.arrow_forwardSome farmers use ammonia, NHS, as a fertilizer. This ammonia is stored in liquid form. Use the particulate perspective to show the transition from liquid ammonia to gaseous ammonia.arrow_forwardConvert the boiling temperature of gold, 2966 C, into degrees Fahrenheit and kelvin.arrow_forward

- An 85.0 g piece of copper is heated to 98.7 degrees C.The copper is then quickly put in to water that was at 20.7 degrees C and the temperature of the water rises to 26.4 degrees C.What is the mass of water?arrow_forwardConvert 65°C to kelvins.arrow_forwardC(s,diamond)+H2O(g)→CO(g)+H2(g)C(s,diamond)+H2O(g)→CO(g)+H2(g) Express your answer in joules per kelvin to one decimal place.arrow_forward
- 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%?arrow_forwardEthylene 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?arrow_forwardConvert the boiling temperature of liquid ammonia. 28.1 F, into degrees Celsius and kelvin.arrow_forward
