Molar mass is the mass of one stable molecule of a compound, that cannot join with another molecule of the same kind to form a new one, while an empirical formula is the molecular formula in its simplest form. E.g. empirical formula of ethene is CH2while its molecular formula is C2H4.

B) convection
Explanation:
Once the sun's energy reaches the earth's atmosphere by radiation, it is circulated within the atmosphere and oceans through convection.
The energy of the sun on earth is moved between the ocean and the atmosphere by air around us.
- Heat transfer in fluids is by convection.
- It involves the actual motion of the particles of medium from one place to another due to differences in temperature and density.
- Air close to the surface of the ocean is less dense and hot due to high temperature.
- The air rises and it is replaced by colder air masses.
- This exchange leads to the development of convective cells.
- This moves the energy of the sun between the atmosphere and the ocean surface.
