Explanation:
Entropy refers to the degree of disorderliness of system. Basically it refers to how random a system is.
Gong through the options.
A. The phase change is from solid to liquid. Liquid has a greater degree of disorderliness compared to solid hence entropy is increasing.
B. The phase change is from solid to gas. Gas particles has a greater degree of disorderliness compared to solid hence entropy is increasing.
C. The phase change is from aqueous to liquid. Aqueous solutions has a greater degree of disorderliness compared to liquid hence entropy is decreasing.
D. The reactant side has; solid + gas. In the product side, there is only gas. The product side has a greater degree of disorderliness hence the entropy is increasing.
E. The entropy of the product is greater than the entropy of the reactants hence entropy is increasing.
F. The phase change is from aqueous to solid. Aqueous solutions has a greater degree of disorderliness compared to solid hence entropy is decreasing.
Answer:
they just add heat, then it turns to water vapor
Explanation:
The first h20 is water the arrow represents adding heat, and the second h20 represent water vapor (water as a gas)
The Ancient Egyptians used simple sundials and divided days into smaller parts, and it has been suggested that as early as 1,500BC, they divided the interval between sunrise and sunset into 12 parts. ... Known as a clepsydra, it uses a flow of water to measure time.
