I wanted to quote sophiecentaur but i quoted twice.

Failed again, sheesh

Thanks for the answer. I am sorry that I didnt understand the first time. Its just because I am not well taught in the scientific language. I guess ill have to translate it to latvian. Thanks again really, this might earn me a 10/10 in physics.

What I want to know more is about the normal thermometer. The bulb mercury detaches from the column mercury and my guess is that its because of surface tension or interaction between molecules, whether it would be mercury mol and glass mol or mercury mol and mercury mol. The problem is that i...

Why does it detach?

Can you explain what constriction?

I am still looking for the answer to the question : " Mercury expands in a thermometer when temperature is in increased, why doesn't it reduce in size when its been in a lower temperature for a long time?"

You can only shake the mercury off when you need to measure the temperature again. The time it contracts is very long i suppose since after a week it will still be roughly the same.

Why does mercury in a thermometer expands when we increase the temperature but it doesn't go down after cooling? Why does it just stay there?
