Entropy is defined by the equation:
dS = δQ/T
where
S is entropy
("d" and δ are mathematical symbols for differential quantities)
Q has units of energy - such as Joules
T has units of thermodynamic temperature - such as K
Since Joules are generally considered the SI unit for energy and K is the SI unit for temperature, entropy will therefore have units of J/K or J∙K-1 if you want to use SI units. It could just as legitimately be given in calories/K or BTU/°R since both of those have units of energy divided by thermodynamic temperature.

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
What happens to the entropy in the reaction?
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
Does diffusion increase the entropy of a solution?
Yes. Diffusion will increase the entropy.
What reaction would have an increased entropy?
At high temperature the entropy increase.
What is the scientific measure of disorder is called?
This is called entropy.
What is the measure of disorder and randomness?
Entropy is the measure of system randomness.
How does the entropy change in the reaction 2c3h6g 9o2g 6co2g 6h2og?
The entropy change in a reaction can be calculated by comparing the entropy of the products to the entropy of the reactants. Without specific entropy values provided, it is difficult to determine the exact change. However, in general, the entropy change is positive in reactions where the products have higher entropy than the reactants, indicating an increase in disorder.

What are the units of entropy and how do they relate to the measurement of disorder in a system?
The units of entropy are joules per kelvin (J/K). Entropy is a measure of disorder in a system, with higher entropy indicating greater disorder. The relationship between entropy and disorder is that as entropy increases, the disorder in a system also increases.
What state of matter has the least entropy?
entropy is the measure of randomness of particles higher is randomness higher is the entropy so solids have least entropy due to least randomness.
How do you revers entropy?
Entropy, as far as we are aware, cannot be reversed.
What happens as a solution becomes diluted in entropy?
Its entropy increases.
What is the physicists term for a measure of amount of disorder?
Entropy
The amount of decay or disorder in a system is called?
Entropy
When was Port Entropy created?
Port Entropy was created in 2009.
