Depend on which chemical and which worm. A common earthworm will die instantly if sprayed with acetone. Pyrethrins will take a while to kill most flying insects, but more potent chemicals will kill them in a moment.
The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.
If a chemical comes in contact with your skin, flush the affected area with lukewarm water for at least 20 minutes. Do not use hot water, as it can cause skin damage. Seek medical help if irritation persists or if the chemical is corrosive.
Stainless steel instruments can be sterilized by using methods such as autoclaving, chemical sterilization, or dry heat sterilization. Autoclaving is the most common method where instruments are exposed to high pressure steam at a specific temperature for a set amount of time to kill microorganisms. Chemical sterilization involves immersing instruments in a solution of chemicals to kill pathogens, while dry heat sterilization uses high temperatures in an oven-like device to achieve sterility.
