Question 19Gas Turbine - Assistant Engineer
70% to passWhich of the following is the definition of absolute temperature?
ATemperature measured with reference to 0 degrees Fahrenheit.
BTemperature measured with reference to 0 degrees Celsius.
CTemperature measured with reference to 273 degrees Rankine.
DTemperature measured with reference to the theoretical temperature at which all molecular motion stops.
AI Explanation
The correct answer is D) Temperature measured with reference to the theoretical temperature at which all molecular motion stops. Absolute temperature is defined as the temperature measured with reference to the theoretical temperature at which all molecular motion stops, which is 0 Kelvin or approximately -273.15 degrees Celsius. This is the lowest possible temperature and represents the complete absence of thermal energy. The other options, A, B, and C, do not accurately define absolute temperature, as they reference different temperature scales (Fahrenheit, Celsius, and Rankine) rather than the absolute zero point.
