Question

The smell of hot sizzling food reaches you several meters away, but to get the smell of the cold food you have to go close. Which property of matter does this activity show?

• A. Particles of matter have space
• B. Energy of particles of matter increases with increase in temperature
• C. Particles of matter attract each other
• D. None of the above

Answer 1

The correct option is B Energy of particles of matter increases with increase in temperature

Particles of matter are continuously moving from one end to another, thereby transferring smell from one place to another. The reason why the smell of hot sizzling food goes farther than cold food is because the kinetic energy of the particles of matter increases with the increase in temperature. So, particles in the smell of hot food have a higher kinetic energy and hence, move farther than those of cold food.
