Total pressure at a point in a fluid equaling the sum of the gauge and the atmospheric pressures. Pressure measured with the base of zero.
Absolute temperature is the temperature of an object on a scale where 0 is taken as absolute zero which is used as a base. Absolute temperature scales are Kelvin and Rankin. Absolute zero is the lowest temperature at which the system is in a state of lowest possible (minimum) energy. No electronic device can operate at this temperature.
Absolute Zero Temperature
Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.
