Question

Given below are few substances with their boiling points at room temperatures. Which amongst them would evaporate the fastest at room temperature $\left({25}^{\circ }C\right)$?

• A. Water: ${100}^{\circ }C$
• B. Petrol: ${210}^{\circ }C$
• C. Acetone: ${56}^{\circ }C$
• D. Sanitizer: ${78}^{\circ }C$

Answer 1

The correct option is C Acetone: ${56}^{\circ }C$

Boiling point refers to the temperature at which a liquid starts getting converted to its vapours, at constant pressure. Lower the boiling point, faster will be the evaporation.

Out of the given substances, acetone has the lowest temperature $\left({56}^{\circ }C\right)$ and hence, will evaporate the fastest.
