Answer:
1: At temperatures below 542.55 K
2: At temperatures above 660 K
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the Gibbs free energy, it is possible to write the following expression:
Whereas ΔG=0 for the spontaneous transition. In such a way, we proceed as follows:
1:
It means that at temperatures lower than 542.55 K the reaction will be spontaneous.
2:
It means that at temperatures higher than 660 K the reaction will be spontaneous.
Best regards!
The reason why it is not considered this is because the material was made in a lab, not through nature, which is what is required to be considered as a true mineral.
Answer:
It will take the police car 3.5 hours to travel a distance of 175 miles traveling at a rate of 50 miles/hour.
Explanation:
I am pretty sure the correct answer is C. Water has large heat capacity meaning it can absorb a lot of energy before changing temperature. That helps the body regulate heat since it can be exposed to different environments and experience small temperature changes.
I hope this helps. Let me know if anything is unclear.
