Convection currents in air
Explanation:
The convection currents in air tends to blow out winds towards the water at night.
Convection is a mode of heat transfer commonly found in fluids.
It involves the movement of the particles due to differences in temperature and density of the air.
- The land and water heats at different rate.
- The land absorbs and loses heat quickly because it is a good conductor of heat.
- At night, the shore area is cold.
- The air around is very dense and close to the surface.
- This air mass moves towards the surface of the ocean.
- The ocean has high specific heat capacity and takes a long time to heat and cool.
- At night, as it is loosing heat, the air around warms up and rises shifting land ward.
- This movement of cold and dense air from land and the attendant movement of warm air to the land sets up convection currents in the air.

Answer:
A feasible error could have been the removal of the sample before all water evaporated.
Explanation:
In order to determine the percentage of water in an hydrate, an experiment that could be performed is the heating of the sample until the mass does not change. If the student heated the sample an insufficient amount of time, water will be present in the sample, thus reducing the percentage reported.
A. Convert the 200 mol of water to kilograms of water.
<h3>Further explanation</h3>
Molality (m) shows the number of moles dissolved in every 1000 grams(1 kg) of solvent.
m = Molality
n = number of moles of solute
p = Solvent mass (gram)
or
solute = 10 mol NaCl
solvent = 200 mol water⇒Convert to kilograms of water.
