5) Entropy a. Predict whether entropy would increase or decrease for the following phase changes.

i. H2O(l) ⇒ H2O(g)

ii. H2O(l) ⇒ H2O(s)

b. Predict whether the entropy would increase or decrease for the reaction 2H2(g) + O2(g) ⇒ 2H2O(g). Explain your answer.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
