lol wow you dont need a piece of equipment to tell when water is boiling... you just watch the water as it heats up and when it starts to bubble its boiling... Ta -dah!
physiological answers tell us that In neurology water may be boiling at a lower substantial rate then non water water.
If you take a pinch of the baking powder and put it in water, it should fizzle. If it does not fizzle, it is no longer fresh.
yes, but i couldn't tell you the mechanics of it.
Fill it with water then empty the water out into a measuring jug (bit by bit if needed) and note the total volume.
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
Yes it can, you can actually try it on a glass by freezing it and puring on boiling water, Bang Goes The Theory on BBC actually showed that if you pure boiling water on a cracked or chipped windscreen it will crack it to even worse state then you have to pay £££££££ for buying a new one so DONT PURE BOILING OR HOT WATER ON FROZEN WINDSCREEN please tell others too, to don't do it
Taste Smell Melting Point Boiling Point Density Residue after it evaporates
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
Actually you don't use "boiling" water, You are supposed to use water that has just quit boiling. The idea is that boiling will damage the leaves (tea is tea leaves) But the water should be just that hot to release the flavour properly and the tea should be allowed to steep for a few minutes and allow the leaves to release all their different flavours naturally with out stirring our damaging the leaves. If it is done properly you get a very nice effect that I am unable to taste, so I use boiling water and stir my tea as I am impatient and can't tell the difference.
The possessive form of the noun teapot is teapot's.Example: The teapot's whistle will tell you when the water is boiling.
Odour, taste, density, and feel (because vinegar is more sticky and thick)
you could pour it out and test to see if there is surface tension. you could put baking soda or detergent in it to see if a reaction happens.
