Question

1. the random movement of molecules is referred to as ______.

brownian movement

dynamic equilibrium

concentration gradient

kinetic energy

Explanation:

• Brownian Movement: Refers to the random motion of particles (like molecules) suspended in a fluid (liquid or gas) due to collisions with surrounding molecules.
• Dynamic equilibrium: A state where the rate of forward and reverse processes (e.g., in a chemical reaction or diffusion) are equal. It is about balance, not random movement.
• Concentration gradient: The difference in concentration of a substance between two regions. It drives diffusion, but it is not the random movement itself.
• Kinetic energy: The energy of motion of an object (or molecule). While molecules have kinetic energy which causes them to move, the term for the random movement is specifically Brownian Movement.

Answer:

Brownian Movement
