Quick Answer. The meaning of a reactive result for a hepatitis B test depends on the type of test performed, according to the Hepatitis B Foundation. The three most common blood tests detect the presence of hepatitis B surface antigens, hepatitis B surface antibodies or hepatitis B core antibodies. Continue Reading.
The Kelvin scale and the kelvin are named after the British physicist and engineer William Thomson, 1st Baron Kelvin , who wrote of the need for an âabsolute thermometric scaleâ. 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, the theoretical absence of all thermal energy, is zero (0 K).
In 1848, Lord Kelvin wrote in his paper, On an Absolute Thermometric Scale, of the need for a scale whereby infinite cold (absolute zero) was the scale's null point, and which used the degree Celsius for its unit increment.he kelvin is defined as the fraction 1â273.16 of the thermodynamic temperature of the triple point of water (exactly 0.01 Â°C or 32.018 Â°F). In other words, it is defined such that the triple point of water is exactly 273.16 K.
