Is boiling water to make tea a chemical reaction or a reversible change?
Yes, because you can cool the water back and it would be normal water again
Does boiling point of water slow down with salt?
no. it does not any impurity in water and other all substances rises its boiling point and slows down its melting point . So salt will raise the boiling point of water rather than lowering it
Does boiled water make tap water cleaner?
The boiling point of tap water is higher than that of distilled water because tap water contains many minerals and bacteria that have higher boiling points than of water in its natural state and thus they collectively increase the boiling point of water. I would suggest researching the boiling points of substances in tap water such as nitrate, chlorine, fluoride, led, etc. because these substances are not in distilled water.
Why the brass need to be immersed in the boiling water before place it in the calorimeter?
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.
In the absences of water what are for itemsthat could cool down a burn?
Butter and aloe vera are two things that can cool a burn down in the absence of water.
Can you re mold a gum shield?
if you mean a mouthpiece yes, dip in boiling water for 35 sec. then dip in cool water not ice water for 3 sec. bite down then in the boiling water for 10 sec. then cool water for 1 sec. and bite down and press you tongue up and pus it against your teeth
What temperature does boiling water freeze?
32 degrees Fahrenheit, or 0 degrees Celsius. Because it is currently boiling, you need to cool it down a lot first.
Is boiling a chemical or physical change?
When water boils, it is a physical change.
What temperature should drinking tea be?
Teas should always be made with boiling water. After that it is down to the individual as to what temperature they like to drink it at, perhaps with milk to cool it down.
Is boiling water to make tea a chemical reaction or a reversible change?
Yes, because you can cool the water back and it would be normal water again
Is it safe to drink boiled water from a hot tap supply?
Yes, any water that has been boiled is very safe to drink. It is important to let the water cool down; do not try to drink water that is still boiling.
Can mints cool down water?
No. Mint does not cool down water. It only creates the senation of something being cool.
What will happen energetically to a cup of boiling hot water that is added to a cup containing a cold piece of metal?
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
How is the boiling of water and the cooling of water vapor a reversible reaction?
when water boils the molecules will get a bigger space inbetween them, which forms a gas (water vapor), when you cool down wator vapor the molecules will get closer together and form a liquid (water)

Does water cool down faster in smaller containers?
yes, if there is less water there is less to cool down
