Q. 9.29 - An Introduction to General, Organic, and Biological Chemistry

Question

Explain the following observations:

a. More sugar dissolves in hot tea than in iced tea.

b. Champagne in a warm room goes flat.

c. A warm can of soda has more spray when opened than a cold one.

Step-by-Step Solution

Answer

(part a)  Since the solubility of solids increases with temperature, more sugar dissolves in hot tea than that in iced tea.

(part b) Champagne in a warm room goes flat. Because the solubility of gases decreases with increasing temperature.

(part c) A warm can of soda has more spray when opened than a cold one. That because the gas solubility of gas is less at high temperature.

Step1: Introduction (part a).

The term "solubility" refers to a company's power to make a solution with another material, the solvent. Insolubility is defined as the inability of a solute to form such a solution.

Step2: Given Information (part a).

The following are the given information to explain the observations:

More sugar dissolves in hot tea than in iced tea. 

Step3: Explanation (part a).

The solubility of solid solutes generally increases as the temperature increases. As a side effect, hot tea has more sugar dispersed than cold tea.

Step4: Given Information (part b).

The following are the given information to explain the observations:

Champagne in a warm room goes flat.  

Step5: Explanation (part b).

At higher temperatures, a gas's solubility decreases. As a result, champagne goes flat in hot weather.

Step6: Given Information (part c).

The following are the given information to explain the observations:

A warm can of soda has more spray when opened than a cold one. 

Step7: Explanation (part c).

Gas solubility decreases with increasing temperature, and the $C{O}_2$ pressure in a warm soda can produces more air freshener than it was when started opening in a cold one.
