Question

The smell of hot sizzling food reaches several metres away, but to get the smell from cold food, we have to get closer. Which of the following reason suits the best?

• A. Lower the temperature, higher the kinetic energy of food particles.
• B. Higher the temperature, higher the kinetic energy of food particles.
• C. Higher the temperatures lower the kinetic energy of the food particles.
• D. Kinetic energy of food particles will not change irrespective to temperature.

Answer 1

The correct option is B

Higher the temperature, higher the kinetic energy of food particles.

As the temperature increases, the kinetic energy of food particle's aroma molecules also increases. However, for a cold food, the aromatic particle would have lesser kinetic energy, resulting in slower movement of aromatic particles in the surrounding. Therefore, we cannot receive the essence of cold food throughout the room.
