The important factor is the kinetic energy of the particles.
- Kinetic Energy and Temperature:
- Particles in matter are constantly in motion.
- As temperature increases, the kinetic energy of these particles also increases, causing them to move faster.
- Diffusion and Smell:
- Smell is carried by particles released from the food.
- These particles spread out through a process called diffusion.
- Faster-moving particles (from hot food) diffuse more rapidly, spreading the smell over a greater distance.
- Contrast between Hot and Cold Food:
- Hot sizzling food releases particles with high kinetic energy, allowing the smell to travel several meters.
- Cold food releases particles with lower kinetic energy, so the smell diffuses slowly and is only noticeable when you are close.
In essence, the heat from the hot food provides the energy needed for the smell particles to travel a greater distance.
