Barbecue (Barbeque) Sauce lasts for. 1 Year. Remember that BBQ sauce, like a lot of other condiments, usually has a best by date and not a use by date. Because of this distinction, you may safely use BBQ sauce to compliment your favorite meals or snacks even after the best by date has lapsed.
Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops-all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.elvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops-all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.
The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale where absolute zero â the coldest possible temperature â is zero kelvins (0 K).he Kelvin scale begins at absolute zero. Each degree on the scale is exactly the same size as a degree centigrade and 0 degrees Kelvin = -273 C. Therefore to convert between the two we have K = C + 273.
