Explain why very small cloud droplets of pure water evaporate even when the relative humidity is 100 percent.
abruzzese [7]

Answer:

Very small cloud droplets of pure water evaporate even when the relative humidity is 100 percent because of the curvature of the droplets surface.

Explanation:

The curvature of a droplet's surface, the molecules present over the surface are much exposed to their surrounding, perhaps less tightly bound by the surface tension force and hence evaporate more speedily than molecules present over the plane surface. For which the saturation vapor pressure of the surface goes up slightly with the curvature of that surface and also with relative humidity. By which the surface is in the equilibrium to more than 100 percent.

In the chemical formula 2so2, how many total atoms of sulfur (s) are there? 1 2 4
babunello [35]
Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms. 


<span>Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms. 
</span>
So your answer is 2

Also remember there is a 2 in front of S meaning there are 2 Sulfurs. 
<span>If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. </span>

<span>Remember the number in front of a element, represents how many atoms there are :)</span>

Below is a bar graph on candy allowance compared to the child's happiness.
rjkz [21]

Answer:

There is no bar graph attached to this question, however, the question can be answered based on the information given in the question.

The answer is A) average level of happiness

Explanation:

In an experiment, the dependent variable is the variable which is measured by the experimenter. It is the variable that responds to changes made to another variable called independent variable.

In the case of this question, it can be determined, even without the bar graph, that the experiment entails how candy allowance affects a child's happiness. Hence, the candy allowance is changed to influence or cause a response in the child's happiness, which is then measured. Therefore, the AVERAGE LEVEL OF HAPPINESS is the dependent variable.
