Explanation:
The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.
Answer:
The statement d) is true: The entropy of the universe is always increased in a spontaneous process.
Explanation:
a), b), c) and e) are false.
a) When no heat exchange occurs between the system and its surroundings
, this process is called an adiabatic process. Because the system does work on the surroundings, w is a negative quantity and there is a decrease in the system’s internal energy (since it cannot exchange heat, it will have to use its internal energy to do work).
b) Breaking a bond will always require energy, whereas forming a bond releases energy. Therefore, if more bonds are broken than formed, the enthalpy of a reaction will be positive.
c) The second law of thermodynamics states that the entropy of the universe increases in a spon
taneous process and remains unchanged in an equilibrium process. Therefore, the entropy of the universe is not always constant.
d) True.
e) According to the Gibbs equation, if ΔH is negative and ΔS is negative, then ΔG will be negative only when TΔS is smaller in magnitude than ΔH. This condition is met when T is small.
Answer:
copper
Explanation:
ions in solution absorb light in the red region of the spectrum. The light which passes through the solution and out the other side will have all the colors in it except for the red.
