I am always trapped in a glass cage.
I usually just sit at the bottom of the cage,
But I climb higher when I get hotter &
Climb down when things get cooler.
What am I?
Mercury in a thermometer.

Consider a well of 116 meter depth and a frog at the bottom of the well. It climbs 9 meter in day time and slides down 5 meter during night. How many days it needs to climb out of the well?
I am usually seen at Christmas, but I am not a stocking or a bell. I am red and white in colour and shaped a bit like the letter L. What am I?
I'm made for one but meant for two; I can be worn for many years but usually just a few; You won't ever need me unless you say you do. What am I?
