It stays at the maximum point so you get an accurate reading
Because there is a constriction to prevent the indicator fluid falling to allow the maximum temperature to be read.
You would likely have different ranges and accuracies for different thermometers. I'm using Fahrenheit. Many newer thermometers would be in Celsius, including those used in hospitals/clinics, or in other parts of the world outside of the USA. A clinical thermometer might read from about 80°F to 110°F, and would be accurate to 1/10 or 2/10 degrees. They can be digital, mercury, or even plastic disposable. They normally have a method to lock in the maximum temperature (like the old ones that you had to shake down). Modern clinical thermometers will either have a disposable plastic cover for the non-disposable variety, or will be 100% disposable. Ocular ear thermometers are a new type of infra-red thermometers. A household thermometer might read from -20°F to 120°F, and might only be accurate to 1 or 2 degrees. If the thermometer is a glass thermometer, the scale is never written on the actual thermometer. A scientific thermometer might have a range up to the boiling point of water... is often in Celsius (-10°C to 110°C), and accurate to a degree Celsius (2 degrees Fahrenheit) or so. A cooking thermometer might have a range of 100°F to 500°F. There may be some glass (or disposable) cooking thermometers, but many are also metal for durability.
six's maximum and minimum thermometer is used to measure the temperature
Because clinical thermometer have a very small range. (20 to 45 degrees Celsius at most) and if placed in boiling water, the water being 100 degrees will cause damage to the thermometer.

No, the temperature of hot tea is substantially higher than the maximum that a clinical thermometer is designed for.

A clinical thermometer typically shows a maximum reading while a lab thermometer typically shows the temperature right now. When you take a thermometer out of a patients mouth (or other place that you are measuring the temperature) you most often want the maximum temperature to keep showing until you reset the instrument. When using a lab oratory thermometer you want the instrument to react as quickly as possible so that changes (up and down) can be noticed and recorded.

JAMES SIX invented the Maximum and Minimum thermometer in 1782.
