The Celsius scale derived on the planet will be the same as that on Earth, because the Celsius scale is independent of the freezing and boiling points of water.

The Celsius scale derived on that planet will not be the same as that on Earth, because the Celsius scale is dependent and derived by using the freezing and boiling points of water.

The Celsius scale derived on the planet will be the same as that on Earth, because the Celsius scale is an absolute temperature scale based on molecular motion, which is independent of pressure.

The Celsius scale derived on the planet will not be the same as that on Earth, but the Fahrenheit scale will be the same, because its reference temperatures are not based on the freezing and boiling points of water.
What is the difference between the freezing point and boiling point of water on the Reaumur scale?

What do latent heats, L_{f} and L_{v}, depend on?
 L_{f} and L_{v} depend on the forces between the particles in the substance.
 L_{f} and L_{v} depend on the mass of the substance.
 L_{f} and L_{v} depend on the volume of the substance.
 L_{f} and L_{v} depend on the temperature of the substance.
