Question

In order to make a mercury thermometer that will measure small changes in temperature accurately, would you

A decrease the volume of the mercury bulb
B put the degree markings further apart
C decrease the diameter of the capillary tube
D put the degree markings closer together
E leave the capillary tube open to the air?

Answer 1

Answer:

The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714).[1] It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb. The volume of mercury changes slightly with temperature; the small change in volume drives the narrow mercury column a relatively long way up the tube. The space above the mercury may be filled with nitrogen gas or it may be at less than atmospheric pressure, a partial vacuum.
