Is water a good choice of liquid for a thermometer ? Why or why not?

Question

I had to do an experiment about how thermometers work i am trying to do a lab report help me out

Answer 1

The reason is that water doesn't react strongly enough to small changes in temperature.......which the ones we experience most often are. The other thing is, that water boils at 100 degrees, which would mean that we couldn't use the thermometer if the temperature would get much above 100 degrees. The thermometer would, if heated enough, explode from the resulting pressure.
So to conlude: We don't use water because of almost no response to changes in temperature at it's liquid state, and because it has a too small interval of relevans.....from 0-100 degrees.

The thermometer is an isolated system when it comes to pressure, so no eveporation of the liquid inside will take place.....so it's nonsense what the guy above says.

Answer 2

No.. water is not a good choice of liquid for a thermometer.

First - it's hard to see (unless it's colored).. and then it doesn't expand that much until it's heated to high temperatures..

I think it's the second reason why water isn't used for thermometers. It doesn't respond too much to slight temperature variations, so it's not good for measuring temperature.

Answer 3

Have you ever wandered what's inside a thermometer and why? Thermometers have mercury inside, why? Why not any other liquid? Mercury is used mainly because it evaporates less, or it doesn't, like the other liquids.
In conclusion water is not a good idea to use because it evaporates and it wouldn't be very effective in measuring temperature.
This is just one reason I hope it helps somewhat.
