The smell of alcohol is not a physical change; rather, it is the result of the volatile compounds in alcohol evaporating into the air. When alcohol evaporates, it changes from a liquid to a gas, which can be detected by our sense of smell. This process is a physical change, as it involves a change in state without altering the chemical composition of the alcohol itself.
Rubbing alcohol evaporating is absorbing energy. As the rubbing alcohol transitions from a liquid to a vapor state, it needs to overcome the intermolecular forces holding the liquid together, which requires energy input.
spontaneous
Cutting down a tree. shredding of paper as well as same of the irreversible change
Boiling or Evaporating
Yes, this change is reversible.
As I have learned, it is an irreversible change, so no its not a reversible change.
No. It is a physical change as the actual compound does not change, only its state does.
Is a physical change as the alcohol is changing states

irreversible change is called a physical change.
It is an endothermic process.
