The students in Ms. Hill's science class were investigating the properties of water. Juan dipped a finger in a beaker of water; Sally dipped her finger in a beaker of alcohol. They both streaked the lab bench with the liquids on their fingers and watched to see which liquid disappeared or evaporated first. The alcohol evaporated quickly, leaving the water streak on the lab bench for several minutes. What unique property of water was illustrated by this simple experiment? A) buoyancy B) specific heat C) surface tension D) capillary action
