Why does hot soup taste more delicious than cold soup?
- 1Because the adhesive force decreases at higher temperatures.
- 2Because heat increases the density of the soup.
- 3Because hot soup has higher viscosity, which enhances its flavor.
- 4Because the surface tension of hot soup is lower, allowing it to spread easily over all parts of the tongue.✓
Correct answer
Because the surface tension of hot soup is lower, allowing it to spread easily over all parts of the tongue.
