Answer:
There are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. This evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. This causes the seawater to become denser.
<u>Answer:</u>
<em>One mole of a substance forms Instead of standard atmospheric pressure and temperature from its pure elements{ conditions being the same} then this change and enthalpy is known as </em><em>enthalpy of formation.</em>
<u>Explanation:</u>
The equation of this formation can let us know what actually happens
ΔH = ΔHf(products) - ΔHf (reactants)
Hence we can say this change in enthalpy formation is the difference between the sum of product and sum of reactants.
