Question

In which of the following diffusion occurs at faster rate?

• A. Air
• B. Salty water
• C. Sugar solution
• D. Drinking water

Answer 1

The correct option is C

Sugar solution

Let us try to understand the diffusion with an example. Diffusion in gases is faster compared to dense liquids. When chemicals, like the smell of perfume or burning toast, are let loose in a room, the particles mix with the air particles. The gas particles are free to move quickly in all directions. They eventually spread through the whole room. This is an application of diffusion of gas.
