Does the amount of water affect boiling point?
Water, for example, reaches the standard atmospheric pressure at 100 degrees Celsius.
This measure is taken at sea level, where the full weight of the earth’s atmosphere presses down upon the water.
As elevation increases, water can boil at a lower temperature..
Why you should never reboil water again?
However, if you boil the water too long or reboil it, you risk concentrating certain undesirable chemicals that may be in your water. Examples of chemicals that become more concentrated include nitrates, arsenic, and fluoride. There is a concern that reboiled water may lead a person to develop cancer.
What bacteria can survive boiling water?
Although, some bacterial spores not typically associated with water borne disease are capable of surviving boiling conditions (e.g. clostridium and bacillus spores), research shows that water borne pathogens are inactivated or killed at temperatures below boiling (212°F or 100°C).
What liquid has the highest boiling point?
1 AnswerAcetone 56.0 ∘C .Ethanol 78.5 ∘C .Peanut oil 230 ∘C .Glycerol 290.0 ∘C .
What increases boiling point?
The key thing to consider here is that boiling points reflect the strength of forces between molecules. The more they stick together, the more energy it will take to blast them into the atmosphere as gases. … Boiling points increase as the number of carbons is increased. Branching decreases boiling point.
How do you know what has the highest boiling point?
The stronger the intermolecular forces in the liquid, the more heat it takes, and the higher the boiling point. Remember that all molecules experience a weak intermolecular attraction called the London dispersion force.
Is it bad to boil the same water twice?
Generally, boiling water, allowing it to cool and then reboiling it does not present much of a health risk. … It’s best if you don’t let water boil down, which concentrates minerals and contaminants and if you reboil water, it’s better to do it once or twice, rather than make it your standard practice.
How long does it take to boil 2 cups of water?
about 5 minutesOn a stove it would take about 5 minutes to boil 2 cups of water, depending on the stove and the factors I mentioned before. Usually it’s 2 minutes per cup of water. It would take a lot longer to boil water on a grill. In a microwave, it would take about 1.5 to 2 minutes to boil 2 cups of water.
