When water becomes ice the entropy decreases does this contradict the second law?

No, because the entropy of the surroundings must increase more than the decrease in the water->ice transition, thus the net change in the entropy of the universe is positive, consistent with the second law.

When water becomes ice and the entropy decreases does this contradict the second law of thermodynamics?
No, Else there wouldn't be a second law of thermodynamics. You cannot look at the ice as something that is by its self. Something froze the ice. Something gained heat the ice lost. If these two things are working towards equilibrium, they are increasing in entropy.
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
What is another name for the second law of motion?
entropy F=ma
What law states that entropy tends to increase over time?
The Second Law of Thermodynamics.
What does the 2nd Law of Thermodynamics say about Direction of heat transfer?
In nature heat only moves naturally from warmer systems to cooler systems. One direction only. Never naturally from something cold into something hot. We can pump heat out of a system by doing work on it, such as a refrigerator where the refrigerant is compressed - making it much hotter than the surroundings - then letting it give off heat to the surroundings, then expanding it across a valve where the evaporation and expansion causes it to get colder than the inside of the fridge - then allowing it to absorb heat from the inside of the fridge, then sending it back to the compressor to start all over again.

What statement best describes the second law of thermodynamics?
The entropy of the universe is increasing
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
What causes entropy to change when a solute dissolves in a solvent?
The solute becomes less ordered. (apex)
The tendency of nature to go toward a state of disorder is called?
It is called entropy, the second law of thermodynamics.Horse Isle Answer: entropy
Is the tendency of a system to become more disordered?
Assuming this is a chemistry question... The entropy of the system increases, as entropy is considered a measure of randomness of a chemical system. The universe favors entropy increases.
Can you decrease the entropy if yes then how and if not then why?
You cannot reduce entropy because entropy increases (Second Law of Thermodynamics), if you could, we could have perpetual motion. When work is achieved energy is lost to heat. The only way to decrease the entropy of a system is to increase the entropy of another system.
Is entropy closely related to the 1st law of thermodynamics?
It is related to the 2nd law of thermodynamics
The amount of useable energy decreases when?
The quality of energy decreases when you use it due to the second law of thermodynamics. Essentially, the energy spent from various reactions is processed, which reduces the amount of work needed to extract it.
Which thermodynamic law has to do with entropy?
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
What is another name for the second law of motion?
entropy F=ma
According to the second law of thermodynamics does entropy increase in a cold system?
That depends on what you mean by "cold" system. Entropy in any system can do one of three things: increase, decrease, or remain constant. If the system is closed, then entropy will only ever increase. If the system is open, entropy within it can do any of the three, provided there is a corresponding change in entropy outside the system (energy must come from or go to somewhere to effect an entropy change). The absolute amount of energy in the system makes no difference to the entropy of it. It is whether you have an open or closed system that counts.
