Which statement about the thermodynamic temperature scale is false?
AIt is the standard temperature scale adopted for scientific measurement.
BIt has one fixed point which is the triple point of water.
CIt measures in kelvin, symbol K which is the SI unit of temperature.
DIts fixed point is called absolute zero and it is measured at atmospheric pressure.
Explanation: Statement D is false: absolute zero is not measured at atmospheric pressure; the thermodynamic scale uses the triple point of water as its fixed point.
