Question

Question:4) Which of the following statement is correct?
A)
Diffusion is fastest in gases and slowest in solids.
B) Diffusion doesn't take place in solids
C)
Diffusion takes place from lower concentration to higher concentration
D) O Diffusion is fastest in liquids

answer as fast as you could to mark as brainlist​

Answer 1

Answer:

The molecules of gas have more kinetic energy than liquid molecules and are smaller. Fluid diffusion is slower because the particles move slower in a fluid. When the temperature is changed, it occurs quicker.

Explanation:

A) Diffusion is fastest in gases and slowest in solids

is the correct answer.

Answer 2

A)

Diffusion is fastest in gases and slowest in solids.

• Diffusion in a gas is faster because the kinetic energy of particles in a gas is much higher than in a liquid, which causes the particles to move faster.
• Thus, the diffusion of gas particles is easier and faster. Solids are solids: liquids are less dense than solids.
• When comparing solid, liquid, and gaseous bodies, gases diffuse the fastest, while solids diffuse the slowest.
• Gases diffuse quickly because the attractive forces between particles are very small or negligible, and there are large gaps between particles.
• The distance between particles in gases is greater than in liquids, so diffusion in gases is faster than in liquids.
• Therefore, the kinetic energy is greater for gas particles, so gas diffusion is faster than liquids.
• Hence correct option is A Diffusion is fastest in gases and slowest in solids.
