How do you change 'K' miles to standard miles?
Is the question how do you convert Kilometers to miles? If so, here's the formula: (Number of kilometers) / 1.6 = (Number of Miles)
[from wikipedia] The standard enthalpy of formation "standard heat of formation" of a compound is the change of enthalpy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 degrees Celsius). Its symbol is ΔHfO.
Look up in a table the standard molar entropies of the reactants and the products. This is usually abbreviated at S0, and is in units of J/(mol*K) Use Hess's Law, which states that the change in entropy of a reaction is equal to the sum of the standard entropies of the products (multiplied by the coefficients from the balanced equations) minus the sum of the standard entropies of the reactants (multiplied by the sum of…
273.15 K = 0 celcius or "centigrade". Kelvin is a temperature scale in which zero occurs at absolute zero and a change in temperature of one kelvin degree is equal to a temperature change of one celsius degree. At standard atmospheric pressure water freezes at 273.15 K (0o C) and boils at 373.15 K (100o C).
How far did each run if Kevin ran 4 miles more than Steve the sum of the distance they ran was 22 miles?
Standard for any vehicle 5,000 miles or every 3 months which ever comes first. Depends on where and how you drive the vehicle. If you do mostly in town or any off road driving, I would change it every 3,000 miles or 3 months. If you do mostly highway driving, then I would go with 5,000 miles or 6 months. It also depends on if you use Conventional or Synthetic oil. With Synthetic the interval…
The dashboard oil change-reminder light is calibrated to turn on 7,500 miles after it was last re-set- and it should be re-set at each oil change. This is probably a good mileage to change 'standard' motor oil and filter. However, if you use so-called 'high-mileage' synthetic oil, you can probably get at least 10,000 miles between oil and filter changes UNLESS you drive in severe climates or under severe conditions.
