This will depend on the source of your water. In most developed countries, it is not necessary to boil water before freezing it for ice cubes because the water is safe to drink. However, in developing countries that don't have consistent safe pathogen-free water, you should boil the water to kill any of the bacteria in it before freezing it into ice cubes.
To get bubbles out of ice cubes, try using boiled or distilled water to make the ice cubes. This removes impurities that could cause bubbles. Another method is to let the water sit for a few minutes before freezing, allowing any bubbles to rise to the surface and pop.
Contaminants could enter the water supply when a water main breaks, making it necessary to boil the water before drinking or cooking with it. Boiling water rids the water or bacteria and other harmful contaminants.
You dont need stock cubes to make spaghetti... Boil water, add pasta, cook until it's the right texture for you, drain & eat
Cold water is better for making ice cubes because it freezes faster than hot water due to its lower initial temperature. Cold water also tends to make clearer ice cubes compared to hot water, which may have impurities that cause cloudiness.
yes
you need to boil the water first then add the noodles
yes, you can. for every cup of water you put in one bullion cube (or one tsp. of granules) and boil.
water vapor is it really ...
If you boil water long enough, all the water will evaporate. However, since you posted your question in the Homebrewing category, let's answer the question with that in mind. If you're making a 5-gallon batch, you can expect to lose at least a gallon during the 90-minute (or longer) boil. When I'm making five gallons, I don't actually boil the whole five gallons. I usually boil three to four gallons and then add enough sterilzed water after the boil to equal five gallons. This helps in the rapid cooling process, which is essential in causing the "cold break," an important step in beer making.
Yes, it's recommended to boil water before adding it to your betta's bowl to remove impurities and make it safe for your fish. Allow the water to cool down to room temperature before adding it to the bowl to avoid shocking your betta.
The pH depends on the temperature.
If it is in boiling water the egg will cook, but the egg will cook before the water in the egg boils.
