When is the change in entropy zero?
The change in entropy is zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
According to the second law of thermodynamics does entropy increase in a cold system?
Yes, according to the second law of thermodynamics, entropy tends to increase in a closed system. In a cold system, if the temperature is below the surroundings, the heat can flow from the surroundings to the system, increasing the system's entropy.
Which thermodynamic law has to do with entropy?
The second law of thermodynamics is closely related to entropy, stating that the total entropy of an isolated system can never decrease over time. This law provides a direction for natural processes, indicating that systems tend to move towards higher entropy states.
What is the relationship between entropy and energy?
Entropy is a measure of disorder or randomness in a system, while energy is the capacity to do work. The relationship between entropy and energy is that as energy is transferred or transformed in a system, the entropy of that system tends to increase. This is known as the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy of a closed system will always increase over time.
Is the entropy of the universe increasing?
Yes, the entropy of the universe is increasing over time, according to the second law of thermodynamics. This law states that in any isolated system, the total entropy, or disorder, will always increase or remain constant, but never decrease.
When is the change in entropy zero?
The change in entropy is zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
When does the change in entropy equal zero?
The change in entropy equals zero when a process is reversible, meaning that the system and surroundings return to their original state without any net change in entropy.
How can one determine the entropy change in a system?
One can determine the entropy change in a system by calculating the difference between the entropy of the final state and the entropy of the initial state, taking into account any heat transfer and temperature changes.
According to the second law of thermodynamics does entropy increase in a cold system?
Yes, according to the second law of thermodynamics, entropy tends to increase in a closed system. In a cold system, if the temperature is below the surroundings, the heat can flow from the surroundings to the system, increasing the system's entropy.
Why is burning an irriversible change?
Just like any other change, entropy increases. That means that you would need ADDITIONAL free energy to reverse the burning.

When someone order something don't he reduce entropy of the universe?
No. You can reduce the entropy of some system, but that will be at the cost of an entropy increase somewhere else. This is because it costs energy to put something in order. The TOTAL entropy in the Universe will always increase. For example, the entropy on planet Earth probably remains more or less constant over millions of years - but we do so using energy, mainly from the Sun, and the fact that energy from the Sun radiates into space is an increase of entropy; much greater than any small change of entropy on our planet.
How can one determine the free energy change in a system without any cost involved?
One can determine the free energy change in a system without any cost involved by using the equation: G H - TS, where G is the change in free energy, H is the change in enthalpy, T is the temperature in Kelvin, and S is the change in entropy. This equation allows for the calculation of free energy change based on the enthalpy and entropy changes in the system at a given temperature.
Which would represent an increase in entropy?
thawing
Will milk explode when put any mint candy?
No it will not explode.
What is heat death how you can relate this term to entropy?
Heat death is a hypothetical situation in which there is no more usable energy in the Universe. In relation to entropy, it means that entropy is at its maximum - it can't increase any more.
When could soda explode?
soda could explode at any time!!!
