Fixed points thermometer
WebTemperature fixed-points. Temperature fixed-points are temperature points based on the natural freezing and melting temperatures of pure materials. The most common fixed-point is the melting point of water. … WebIf an alcohol thermometer and a mercury thermometer have the same two fixed points, namely the freezing and boiling point of water, their readings will not agree with each other except at the fixed points, as the linear 1:1 relationship of expansion between any two thermometric substances may not be guaranteed.
