it would probably crack
There will be a sudden change in temperature and it is likely that the thermometer may even break.
it will buse
yes, heat over boiling water and once liquified, re-form to your liking
Sublimation, boiling, condensation, melting and freezing. One might include evaporation, though that does not happen at a particular temperature.

You might turn off the freezer.

it might decrease or increase depends on the impurities added.:D
Normally not. Only if the temperature rises above the maximum specified value it might happen, if the device is not being switched off by an over-temperature safety switch. Under normal circumstances it only affects the energy used by the freezer.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
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.
To measure temperature. A gauge can be used instead of a thermometer, and is generally used in industry where a thermometer might be too fragile
