Question

Oxygen (O) is a gas at room temperature. Room temperature is 75° F. Which of the following statements is true?

1.) The melting point of oxygen is warmer than room temperature
2.) The boiling point of oxygen is warmer than room temperature
3.) The boiling point of oxygen is colder than room temperature
4.) The melting point of oxygen is above the boiling point

Answer 1

It is a gas at room temperature, so it must have already been boiled. Therefore the boiling point must be less that (cooler) than room temperature so the answer is 3
