You are asked to determine the identity of an unknown liquid and can measure only one physical property. you heat the liquid and record that the liquid turns to vapor at 100°c. this demonstrates which physical property? question 1 options:

This physical property is called evaporation and was caused by the boiling point of the liquid.

Explanation:

Evaporation is the passage from liquid to gaseous state. It occurs on the free surface of liquids, slowly and gradually, when the temperature at which the liquid (or other substance) is subjected reaches its boiling point.

A substance in its liquid state has less cohesive force between its atoms than in its solid state. In this state, the molecules are further apart, in constant agitation, and move within the liquid at different speeds. In this way, the particles with higher velocity, when they reach the free surface of the liquid, can escape to the gaseous state.

The higher the temperature, the faster the evaporation will be. For the higher the temperature, the greater the kinetic energy of the particles. This way more particles will escape from the liquid surface.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

the answer would be   10%
