K physics variable value
WebWhen doing physics problems, you'll often be required to determine the numerical value and the units of a variable in an equation. The numerical value usually isn't too difficult to get, but for a novice, the same can't be said for the units. This self-instruction unit deals with dimensional analysis, which is a useful method for determining the units of a variable in … Web12 jan. 2024 · The SI value of the gas constant is exactly 8.31446261815324 J⋅K −1 ⋅mol −1. Usually, the decimal is rounded to 8.314. The Gas Constant is the physical constant in the equation for the Ideal Gas Law : PV = nRT P is pressure, V is volume, n is the number of moles, and T is temperature. Rearranging the equation, you can solve for R: R = PV/nT
