Which of the following is closest to the melting point of oxygen in kelvin?
A
54 K
B
273 K
C
0 K
D
90 K
Verified step by step guidance1
Understand that the melting point of a substance is the temperature at which it changes from solid to liquid under standard pressure.
Recall or look up the approximate melting point of oxygen, which is a diatomic molecule (O\_2) and a gas at room temperature.
Note that oxygen liquefies and solidifies at very low temperatures because it is a small molecule with weak intermolecular forces (London dispersion forces).
Convert the melting point from Celsius to Kelvin if necessary, using the formula \(T(K) = T(^\circ C) + 273.15\).
Compare the given options (273 K, 0 K, 90 K, and 54 K) to the known melting point of oxygen and select the closest value.
