Question

why does diffusion not require any energy? because particles are always in motion, so movement occurs naturally because solutes provide energy for the process because water has inherent energy which facilitates the process

Explanation:

To determine why diffusion doesn't need energy, we analyze the options:

• The first option states particles are always in motion (due to kinetic energy), so movement from high to low concentration (diffusion) happens naturally without external energy.
• The second option is incorrect because solutes don't provide energy for diffusion.
• The third option is wrong as water's inherent energy isn't the reason; it's the natural motion of particles.

Answer:

A. because particles are always in motion, so movement occurs naturally
