Answer:
8 gram
Explanation:
in case of NaOH, normality=molarity
so normality=molarity×acidity or basicity(in case of NaOH it's 1)
then
weight of NaOH required = volume in ml × equivalent weight × normality / 1000
so
1000× 40× 0.2/1000
=8 gram
Upwelling
Explanation:
The rise of deeper water to the surface is called upwelling.
Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.
- This occurs usually along the short where wave action is very prevalent.
- Surface wave pushes away warm water.
- Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
- This nutrient rich water supports biological activities because they are rich.
- Wind along the coast can also force surface water down.

This is because solids have less energy than liquids do, hence it takes more energy to excite a solid into its gaseous phase than it does a liquid.
When opposed to merely reducing their separation, from solid to liquid, the energy needed to totally separate the molecules as they move from liquid to gas is substantially higher. The latent heat of vaporization is therefore bigger than the latent heat of fusion for this reason.
<h3>
What is heat of sublimation?</h3>
The amount of energy required to change one mole of a substance from its solid to its gaseous state under particular conditions—typically the standard ones—is known as the enthalpy of sublimation or heat of sublimation (STP). A solid's worth is based on its cohesive energy.
<h3>
What is heat of vaporization?</h3>
The term "enthalpy of vaporization," which is often referred to as "heat of vaporization" or "heat of evaporation," refers to the amount of energy that must be applied to a liquid substance in order to cause a part of that substance to transform into a gas. Vaporization's enthalpy varies with the pressure at which the transition takes place.
