Chapter 9: Q. 9.29 (page 298)
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.
Short 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.
