Question

What would happen if the glass of a thermometer expanded more on the warming than the liquid did in the tube?

Answer 1

Hint: A glass thermometer comprises a stem and bulb. At the point when the thermometer bulb is put close to body tissue, the mercury retains a portion of the body's warmth. As the mercury gets hotter, it grows. Since the mercury has no more space in the bulb, a portion of the mercury is constrained into the shaft.

Complete answer:
Fluid in-glass thermometers depend on the rule of thermal expansion of substances. A fluid in a glass tube (called a capillary) grows when warmed and contracts when cooled. In the event that the glass was to expand more than the fluid, the fluid level would fall comparative with the tube wall as the thermometer when it is warmed.

On the off chance that the fluid and the tube material were to expand by equivalent sums, the thermometer couldn't be utilized on the grounds that the fluid level would not increase or decrease with the change in temperature.

In conclusion, if the glass part of a thermometer expanded more on the warming than the liquid did in the tube, the scale present on the thermometer would be reversed in such a way that the higher values of temperature will be found closer to the surface.

Note: Some might think that the mercy overflows and forms harmful substances, but that is not the case here. It is important to understand and study the parts, working and function of the glass thermometer. The fluid/ glass thermometer is one of the most widely used thermometers. It has very high accuracy and is also user friendly.
