Question
Why do we say that sliding a book to a halt across the table is an "irreversible" process?
A.Because you can never slide the book back again
B.Because energy is destroyed in this process
C.Because the book will never return to motion on its own
D.Because the momentum of the book is transferred to the table
E.Because of conservation of angular momentum
If the laws of nature (conservation of energy etc.) allow several possible outcomes, which is the most likely to occur?
A. The outcome with the most momentum B. All outcomes are equally likely C. The outcome with the smallest energy D. The outcome with the largest energy E. The outcome with the least total momentumExplanation / Answer
C.Because the book will never return to motion on its own
a process is said to be reversible when it comes to its initial stage on its own . but it will
no happen here , so thats why it is irerevsible.
2. If the laws of nature (conservation of energy etc.) allow several possible outcomes, All outcomes are equally likely .
