When making tea, the water is supposed to have different temperatures for different types of tea. However, boiling at 100 degrees C is supposed to be bad even if the water is cooled afterwards because it “boils away the oxygen” from the water. Could you please

Chemistry Oxygen has a boiling point of 90K, and nitrogen has boiling point of 77K. Which is a liquid and which is a gas at 80K? I tried to look into the phase diagrams, but I still don’t understand. Can somebody please help and explain to me??? THANKS A LOT!!!

The boiling point of the liquid depends upon the pressure of the surrounding. When the liquid is at high pressure, it has a higher boiling point than the boiling point at normal atmospheric pressure. The boiling point of different liquids is different for a given pressure.

Boiling Point of Aqueous Methanol Solutions Jonathan Bollinger, Christopher Eyster, Gregory Trout ABSTRACT We hypothesized that the boiling point of methanol would increase linearly from the traditional boiling point elevation equation.

The boiling point of pure oxygen, O 2, is 90.6 K and the boiling point of nitrogen, N 2, is 77 K. If air is cooled at atmospheric pressure, it remains a gas until the temperature reaches 81.6 K, 9 K below the liquification temperature of pure oxygen. It will be

Diamonds do not melt, they sublime!This means it goes straight from solid to gas! The gas that comes off is carbon dioxide (basically as the carbon gets really hot, it reacts with the oxygen in the air). If you were to heat the diamond in a vacuum, i.e. no air to react with, the diamond would slowly become graphite.

These tests demonstrate how water affects the flavour of tea, but I still wanted to explain it scientifically, to destroy the myth. What happens is that oxygen dissolved in water is released at temperatures much lower than the boiling point. As you can see in the oxygen solubility in water curve below, water looses oxygen in small amounts as you raise the temperature.
