Question

The smell of hot sizzling food reaches several meters away, but to get the smell from cold food, we have to go close. 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 particles increases so the particles move faster. However, a cold food particle has less kinetic energy, so the speed of particle movement in the above case is much slower. Therefore, we cannot smell cold food throughout the room.
