Question

The smell of hot sizzling brownie reaches everyone in a room but it is not the case with an ice cream, because the particles at move faster.

• A. room temperature
• B. high temperature
• C. low temperature

Answer 1

The correct option is B high temperature

As the temperature increases, the kinetic energy of the aroma carrying particles increases, so they move faster. However, for a cold food item like an ice cream, particles have very low kinetic energy, so the movement of particles is very slow or negligible. Therefore, we cannot smell cold food throughout the room.
