Precautions when using a laboratory thermometer

It should be kept upright not tilted.

Bulb should be surrounded from all sides by the substance of which the temperature is to be measured.

The bulb should not touch the surface of the container.

Hope this helps

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
