I would appreciate it if someone could recommend something. I found a boiling point calculator by CalcTool but it doesn't seem that reliable.
The boiling point of a substance can vary at different pressures. At 1 atm, the boiling point of water is 100 degrees Celsius. However, at higher pressures, the boiling point increases, and at lower pressures, the boiling point decreases.
There are several online resources that provide tables and calculators for determining the boiling point of a substance at different pressures. Some common ones include the NIST Chemistry WebBook and the Engineering Toolbox.
While the boiling point at 1 atm can provide a rough estimate, it is not always accurate. It is best to use a reliable source for determining the boiling point at a specific pressure.
As pressure increases, the boiling point of a substance also increases. This is because the increased pressure forces the molecules of the substance to be closer together, making it harder for them to escape into the gas phase. On the other hand, decreasing pressure lowers the boiling point as there is less pressure to keep the molecules together.
Aside from pressure, the boiling point can also be affected by the type of substance, its purity, and the presence of other substances in the mixture. In addition, altitude can also impact the boiling point, as the air pressure decreases at higher altitudes. This is why it takes longer to boil water at high altitudes compared to sea level.
