Q. 3.9 - An Introduction to General, Organic, and Biological Chemistry

Question

Associate the contents of the beakers ( $1$ to $5$ ) with segments ($A$ to $E$ ) on the following heating curve for water: ($3.7$)

Step-by-Step Solution

Answer

The following contents of beakers are associated with the segments using heat curve of water.

Step: 1 Given Information:

Given data are: The figure as:

 

The graph given as

Step: 2 Beaker 1 , 2 :

The beaker one depicts water evaporation, thus both water and vapor exist in the beaker; at boiling point, both water and vapor exist, in the heating curve boiling point is shown at${100}^{\circ }C$   represented by $D$.Water exists in a liquid state above $0^0\mathrm{C}$ and below ${100}^{\circ }\mathrm{C}$, which is represented by $C$ in beaker $2$.

Step: 3 Beaker 3 :

Solid state is represented by Beaker $3$, water exists in solid state below $0^0\mathrm{C}$, solid state is represented by $A$.

Step :4 Beaker 4 :

Beaker $4$ contains a floating solid atop a liquid, therefore both water and ice exist in the beaker; at melting point, both water and its ice exist, in the heating curve, the melting point is shown at $0^{\circ }\mathrm{C}$ by $B$.

Step: 5 Beaker 5 :

Water vapor is represented by Beaker $5$, and water in a gaseous state exists above the boiling point. The state of vaporization of water is illustrated by $\text{ E}$
