<span>The three methods are
wet gas desulfurisation(W)
dry gas desulfurisation(D)
seawater gas desulfurisation.(S)
In method W Calcium carbonate, CaCO3 material is used and material is obtained by quarrying. The solid waste is sold for use in buildings.
In method D Calcium oxide, CaO is used and the material is obtained by Thermal decomposition of calcium carbonate. Solid waste is sent to landfill.
In this method material is obtained from sea water. Liquid waste is returned to the sea.</span>
This is thermodynamics. When you increase the temperature of an object, the particles gain on kinethic energy ergo the move faster. When you decrease it, they slow down.
When you mix the sugar into the tea and stir, it dissolves so you can't see it. Also when you stir the sugar into the tea the taste changes and it turns sweeter.
