The top of the liquid (mercury normally) in the thermometer capillary will be level with 0.

I assume you are asking how the figure was arrived at??
A guy named Celsius was experimenting with his idea for a thermometer, he noted that when he was checking the movement of Mercury in a glass tube it always rose to the same spot in the tube when checked against boiling water. Then when checked against ice it always went to another spot on his little tube.
He marked the glass tube up at 0 degrees Centigrade for the ice and 100 degrees for the boiling water!
This will vary depending on the atmospheric pressure! But we don't really want to go into that do we??

Put a cup of water next to it. If the water freezes, you know your Thermometer is at zero centigrade.

If distilled water freezes, it is at or below 0°C; if it melts it is above 0°C.
Of course, if you are actually looking at a thermometer, the liquid inside will indicate 0°C or 32°F.
By the way, most thermometers these days do not contain mercury, which is highly toxic. Instead they usually contain alcohol with a coloured dye.

thats easy. put it in boiling water, scratch off all the markings down the side and write plonker in their place.

Because it would be cold and the water would be lumpy.

because the mecury is at that level.
