Question
Chapter 12, Problem 37E
Interpretation Introduction
Interpretation:
When acetone and water poured on hand, the substance which produce a cooling effect after evaporation is to be identified and explained with a suitable reason.
Concept Introduction:
In evaporation or vaporization, a substance is converted from liquid state into a gaseous state. Liquids that evaporate easily are volatile, whereas those that do not vaporize easily are non-volatile.
