Can a normal human float in mercury?
No, a normal human would not be able to float in mercury. Mercury is about 13.6 times denser than water, making it extremely dense and heavy. The human body would sink in mercury due to its high density.
What happens to fish and other water life when mercury levels get to high?
When mercury levels get too high in water, fish and other water life can accumulate the mercury in their tissues. Consuming these contaminated organisms can lead to mercury poisoning in animals higher up in the food chain, including humans. High levels of mercury can harm the nervous system, impair reproduction, and have other adverse health effects in aquatic organisms.
A gas thermometer registers an absolute pressure of 305 mm of mercury when in contact with water at the triple point. A) What pressure does it read when in contact with water at the normal boiling poi?
At the normal boiling point of water (100°C), the vapor pressure of water is approximately 760 mm of mercury (1 atm). The gas thermometer, which measures absolute pressure, would read the sum of the atmospheric pressure and the vapor pressure of water. Therefore, if the thermometer initially reads 305 mm of mercury at the triple point, at the normal boiling point, it would read 760 mm of mercury.
Which human activity has had the greatest impact on increasing mercury levels?
Burning of fossil fuels, such as coal, is the human activity that has had the greatest impact on increasing mercury levels in the environment. When coal is burned, mercury is released into the atmosphere and can then be deposited into bodies of water where it accumulates in fish.
How is Mercury filtered out of water?
Better Question: How is mercury separated from water?As it has a lower boiling point than mercury, the water can be evaporated at 100 degrees Celsius (212 degrees Fahrenheit), leaving the mercury behind. Be careful not to continue heating, as it will cause some mercury to evaporate. Alternatively, since mercury is heavier than water, it will sink to the bottom, allowing you to pour the water off the top.
What are the current acceptable levels of mercury in drinking water in Canada?
0.001 mg total mercury per Litre

Why do people need to worry about the mercury levels in the water?
because the mercury will weaken your liver making you in general weaker and so you will die

High levels of mercury can harm the nervous system, impair reproduction, and have other adverse health effects in aquatic organisms.
Why does normal water have lower sodium chloride levels than salt water?
Normal water, such as freshwater in lakes and rivers, typically has lower sodium chloride levels than saltwater because it does not contain significant amounts of dissolved salts. Saltwater, like that found in the oceans, has higher sodium chloride levels due to the accumulation of salts from various sources over time.

How much Mercury was in Sir Isaac Newton?
There is no exact number for the amount of mercury that poisoned Sir Isaac Newton, but it is estimated that he had 15 times the normal level in his body. He also was exposed to high levels of lead.
Can mercury be in well water?
Almost anything that is in the ground your well is drilled into, will be in your water in minute quantities. -This is why it is necessary to get a sample of water tested if you are intending to drink it.
Why is mercury a better liquid to use in manometer than water?
Water can be used up to only 100 degree celsius. mercury can be used 356 degree celsius Water has a tendency to evaporate. The density of water is about 13 times lower than that of mercury, so some pressure levels would need a very large manometer tube.

Does hake have high mercury levels?
On the Natural Resource Defense Council (NRDC) site, hake are placed in the list of fish with the lowest mercury levels. Their mercury levels are similar to that of other common fish such as anchovies, pollock, and salmon.
