A necessary expense is one that is helpful and appropriate for your trade or business. An expense does not have to be indispensable to be considered necessary.
The oceans absorb much CO2 in a process thatâs called hydration. The relation between temperature and CO2 is that CO2 increases lag temperature increases by 800 which is due to sea temperatures. The ability of sea water to absorb CO2 is dependent upon the water temperature.he oceans absorb much CO2 in a process thatâs called hydration.

If the amount of water vapor in the air increases, the relative humidity increases, and if the amount of water vapor in the air decreases, the relative humidity decreases. However, relative humidity is dependent on air temperature, too. If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases. This is because colder air doesnât require as much moisture to become saturated as warmer air.
