The mineras in the water cling to and react with the metals of the pot. Aluminum pans do this frequently.
If you mean 212 oF then this is boiling point of water. If you mean 212 oC then the water has long evaporated into a gas.
It's different for every gas. It also depends on the pressure. You actually need a two-dimensional depiction called a phase diagram. Check out the Wikipedia article on 'vapor'. You also need to consider that most substances will have a non-zero vapor pressure at temperatures below their boiling points and at least down to their freezing points. As long as you're not interested in some pedantic definition of gas which differentiates it from vapor, there is no specific temperature at which a gas turns to liquid, or vice versa. answ2. A gas turns into a liquid at its condensation temperature, or in the reverse direction, a liquid turns into a gas at its boiling point.
The boiling point of water is the temperature at which the vapor pressure of water is equal to the atmospheric pressure. As long as there is liquid water present, the temperature will remain at the boiling point (100 degrees Celsius at sea level), because the energy is being used to convert the liquid water into vapor rather than increasing the temperature.
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
yes, It gets the convection current going faster and makes the water hotter. it also helps to put a lid on with the salt already in the water
Boiling water will produce steam (water vapour). Eventually, if boiled long enough, all the water will have evaporated, with the risk of the bottom of the pan or kettle melting.
If you mean 212 oF then this is boiling point of water. If you mean 212 oC then the water has long evaporated into a gas.
gray water, as long as slinity levels are low and no phytotoxic chemicals are added to the gray water
Boiling water for at least one minute effectively kills most germs.
Boiling water for at least 1 minute can effectively kill most bacteria.
It usually takes a minimum of 10 minutes to sterilize items places in boiling water.
Orzo typically takes about 9-10 minutes to cook in boiling water until it is al dente.
Boiling water can effectively kill weeds by damaging their cells and roots. It usually takes about 30 seconds to 1 minute of exposure to boiling water to kill weeds effectively.
By the time water hits its boiling point the water is safe.
Tomatoes should be blanched in boiling water for about 30 to 60 seconds to easily peel them.
The time it takes for boiling water to cool down to 185º depends on factors such as the initial temperature of the water, the volume of water, and the surrounding environment. On average, it may take around 30-45 minutes for boiling water to reach 185º.
The time it takes for boiling water to cool down depends on factors like the initial temperature, the surrounding environment, and the volume of water. Generally, it can take anywhere from 30 minutes to a few hours for boiling water to cool down to room temperature.
