Chapter 24, Problem 22A
What is the physicist’s term for a measure of messiness?
Expert Solution & Answer
To determine
The physicist’s term used for a measure of messiness.
Answer to Problem 22A
Entropy.
Explanation of Solution
Introduction:
Entropy is a state of disorder or randomness. It is the extensive property of a thermodynamics system.
When collisions increase in a system then the temperature of the system also increases. Due to collisions, a state of randomness occurs that is molecules become disoriented and move irregularly. This tends to messiness in a system. Thus, entropy is the right word to say if a system is messy.
Conclusion:
Thus, the physicist’s term for a measure of messiness is entropy.
