Get started for freeEthylene glycol is the main component in automobile antifreeze. 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 \(\left(-45^{\circ} \mathrm{C}\right.\) and \(\left.115^{\circ} \mathrm{C}\right)\). You wish these points to correspond to \(0^{\circ} \mathrm{A}\) and \(100^{\circ} \mathrm{A}\), respectively. a. Derive an expression for converting between \({ }^{\circ} \mathrm{A}\) and \({ }^{\circ} \mathrm{C}\). b. Derive an expression for converting between \({ }^{\circ} \mathrm{F}\) and \({ }^{\circ} \mathrm{A}\). c. At what temperature would your thermometer and a Celsius thermometer give the same numerical reading? d. Your thermometer reads \(86^{\circ} \mathrm{A} .\) What is the temperature in \({ }^{\circ} \mathrm{C}\) and in \({ }^{\circ} \mathrm{F}\) ? e. What is a temperature of \(45^{\circ} \mathrm{C}\) in \({ }^{\circ} \mathrm{A}\) ?
Define the following terms: solid, liquid, gas, pure substance, element, compound, homogeneous mixture, heterogeneous mixture, solution, chemical change, physical change.
What is the difference between random error and systematic error?
What data would you need to estimate the money you would spend on gasoline to drive your car from New York to Chicago? Provide estimates of values and a sample calculation.
Give four examples illustrating each of the following terms. a. homogeneous mixture d. element b. heterogeneous mixture e. physical change c. compound f. chemical change
