9. an ice tray contains 800 g of liquid water at 0°c. calculate the change in entropy of the water as it
freezes slowly and completely at 0°c. the latent heat of fusion is l= 333 kj/kg.
a. -975.8 j/k
b. -623.2 j/k
c.975.8 j/k
d. 623.2 j/k

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
