Asked by Sarah

If a thermometer bulb is not completely immersed in water, what effect will this have on the measured melting point? Will it be higher or lower than actual?
Answered by DrBob222
The measured melting point probably will be lower than it should be because not all of the mercury in the bulb is subject to expansion/contraction due to the temperature of the liquid. As you have described the post you are measuring the temperature of the water.
