The movement of molecules from high to low concentration, requiring no energy, is called:
اعلی سے کم ارتکاز تک مالیکیولز کی حرکت، جس میں توانائی کی ضرورت نہیں ہوتی، کہلاتا ہے
Answer: Diffusion
Explanation
Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion.
It is the net movement of molecules or atoms from a region of high concentration to a region of low concentration.
This is also referred to as the movement of a substance down a concentration gradient.
