To find the boiling point of liquid hydrogen, we can follow these steps:1. Identify the Chemical Formula: - The chemical formula for hydrogen in its molecular form is \( H2 \).2. Determine the Molar Mass</stro
A characteristic property of a liquid is its boiling point. A sample of a pure liquid will always boil at the same temperature under the same conditions. Increasing the pressure on a liquid makes it harder for it to reach its boiling point, as this pressure keeps molecules from escaping th...
The boiling temperature of liquid oxygen at atmospheric pressure has been measured by means of a platinum thermometer in magnetic fields up to 28.8 kG. After taking into account a rough correction for magnetoresistance of the platinum and for nitrogen impurities in the liquid oxygen, the increase ...
