To determine the substance with the lowest boiling point among hydrogen, oxygen, nitrogen, and helium, we need to consider the boiling points of these elements.
1. Hydrogen (H2): The boiling point of hydrogen is -252.87 degrees Celsius (-423.17 degrees Fahrenheit). It is a very low boiling point, but we need to compare it with the other options.
2. Oxygen (O2): The boiling point of oxygen is -183 degrees Celsius (-297 degrees Fahrenheit). It is higher than the boiling point of hydrogen.
3. Nitrogen (N2): The boiling point of nitrogen is -195.8 degrees Celsius (-320.4 degrees Fahrenheit). It is also higher than the boiling point of hydrogen.
4. Helium (He): The boiling point of helium is -268.93 degrees Celsius (-452.07 degrees Fahrenheit). It is the lowest boiling point among the given options.
Therefore, among hydrogen, oxygen, nitrogen, and helium, the substance with the lowest boiling point is helium (option d).
