What is the formula to calculate deltaS?
Delta S= Sum of Entropy(products)- Sum of Entropy(reactants.
What is the origin of the word entropy?
Greek
When entropy is less than zero the probability of occurrence of such a process in an isolated system is?
I don't think entropy can get less than zero
Can delta s be negative Entropy?
yes
Does the entropy of a system increase over time?
Yes.
What is the lowest entropy?
h20(s)
In states would potassium chloride (KCl) be expected to have the lowest entropy?
solid crystal
What form of carbon dioxide has the lowest entropy?
Solid carbon dioxide, also known as dry ice, has the lowest entropy among the different forms of carbon dioxide. In its solid state, the molecules are tightly packed together, resulting in a more ordered arrangement and therefore lower entropy compared to gaseous or liquid states.
Which state of matter has the lowest entropy?
Higher is the energy of the state, lower will be its rigidity. Hence, we can say that solids have lowest state of energy because they are most rigid and gases have the highest state of energy since they are fluid in nature and don't have any rigidity.
What is the scientific measure of disorder is called?
This is called entropy.
Explain the combined effects of entropy and enthalpy during the melting of ice?
There are two tendencies in nature: things tend to go to the lowest possible energy (enthalph) level (delta H = negative) and the highest possible state of disorder (entropy)
What is true about entropy?
Entropy is not change. Entropy is disorder.
What happens when to the entropy when a solution is made?
The entropy increases.
What is the measure of disorder and randomness?
Entropy is the measure of system randomness.
Which term describes the describes the disorder of random molecular motion?
entropy
Why is entropy irreversible?
It's not that entropy can't be reversed, it's that the entropy of the universe is always increasing. That means that while you can reduce the entropy of something, the entropy of another thing must go up even more so that in total, the entropy goes up.
What does the second law of thermodynamic say about entropy?
The entropy of the universe is increasing
