Answer;
A decrease in the vapor pressure of the liquid.
Dissolving a solute such as potassium hydroxide in a solvent such as water results in a decrease in the vapor pressure of the liquid.
Explanation;
The vapor pressure of a liquid is the equilibrium of a vapor above its liquid.
In other words it is the pressure of the vapor resulting from the evaporation of a liquid above a given sample of the liquid in a closed container.
The vapor pressure of a liquid in a closed container depends on the temperature.
F = M x A
F = 0.25 x 196
F = 49 N
Answer : Option C) Atomic Size
Explanation : The atomic radius of the elements is found to be decreasing if we go from left to right in the modern periodic table. Accordingly, 
increases as the number of shielding electrons present in the atomic nucleus of the periodic elements which lies in the same row remains constant while the number of protons in each atomic shell increases.
The effective nuclear charge of an atom is defined as the net positive charge which is felt by the valence electron of the atomic element.
When 
is observed to decrease, it is seen that the atomic radius grows in size. So, it explains the inverse relationship between both. This phenomenon occurs, because there is more screening of the electrons from the nucleus taking place, which is observed due to decrease the attraction between the electron and the nucleus.
First lets define upwelling
Upwelling- a rising of seawater, magma, or other liquid
In this case, you would be looking at a river, lake, ocean, or other body of water good for fishing.
You'd want to look for a place with upwelling because when there is a rise of water, the sea creatures within it will rise too. So the fish in the bottom of a lake for example would be brought up to the surface of the water or near the surface which is where your fishing rod is trying to grab the fish.
