Here the factor that Elle is controlling is the temperature. So temperature here is the independent variable and the dependent variable is the rate of evaporation of water. Independent variable is controlled during the experiment setup and the outcome of the dependent variable depends on the independent variable.
Answer:
It is better to do chemistry
Explanation:
So that you will learn more of chemicals
Its B i believe, Storms and currents can bring in sediments from other places
A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.
b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times
A.) Periods within the periodic table. :)
