How sensitive is LST Heavy Liquid to slight changes in room temperature?
LST heavy liquid expands and contracts like any other liquid, such as water, and its density varies accordingly. The expansion of LST heavy liquid expansion is only fractionally more than that of water, and the specific gravity of LST heavy liquid is not unusually sensitive to slight changes in room temperature. The density of LST heavy liquid changes by approximately 0.01 g/ml for a 10oC temperature change. Other changes such as evaporation or crystallisation can affect the density. For example, if LST heavy liquid is left with a large surface area open in a draught (such as in a fume cupboard), then evaporation can cause the density to change.
