Question

After analyzing the graph, which statement best describes what is happening in the graph

a) the negative trend of the graph shows oxygen becomes more soluble as the temperature increases
b) the negative trend of the graph shows oxygen becomes less soluble as the temperature increases
c) the positive trend of the graph shows oxygen becomes more soluble as the temperature increases
d) the positive trend of the graph shows oxygen becomes less soluble as the temperature increases

Answer 1

You can see that where the graph starts at (0,15) is it's highest point, and where the graph ends (30,7) is it's lowers point. You can also just by looking at this graph see that as the line trends downwards it must have a negative slope. Also, an increase in temperature also causes an increase in kinetic energy; higher kinetic energy causes more motion in the gas, causing the gas' solubility to decrease. This means that you answer should be (B). Hope that this helps!

Answer 2

so whats the answer to the question because i dont know.and i am taking the same test
