In a shrinking universe heat will increase, but also volume available to place particles will decrease. What happens to entropy when the volume gets very small and the temperature is very high?
Dodging the question...KurtLudwig said:Summary:: Does entropy always increase even in a contracting universe?

I assume you know that entropy can decrease locally , as long as it increases over all in any isolated system. i mention this , because you bring up "entropy at the quantum level". what exactly are you asking?KurtLudwig said:Summary:: Does entropy always increase even in a contracting universe?

Entropy is a measure of the disorder or randomness in a system. It is a concept in thermodynamics that describes the tendency of a system to move towards a state of maximum disorder.
According to the second law of thermodynamics, the total entropy of a closed system will always increase over time. This means that the disorder or randomness of a system will always tend to increase, unless energy is added to the system.
In some cases, it is possible for the entropy of a system to decrease. However, this can only happen if energy is added to the system, such as in a refrigerator. In this case, the decrease in entropy of the refrigerated space is offset by an increase in entropy in the surrounding environment.
The change in entropy of a system is affected by the amount of energy added or removed, the temperature, and the number of particles in the system. Generally, the higher the temperature and the more particles in a system, the greater the change in entropy will be.
Yes, entropy is closely related to the concept of disorder. In a system with high entropy, there is a high degree of disorder or randomness, while a system with low entropy is more ordered and structured. This is why entropy is often referred to as a measure of disorder.
