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).
The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Subtracting 273.16 K from the temperature of the triple point of water (0.01 Â°C) makes absolute zero (0 K) equivalent to â273.15 Â°C (â459.67 Â°F).
