◾️An incence stick is burnt.
◾️A drop of ink is added into a glass of water.
◾Blue ink is dropped on a piece of chalk.
a) In which situation diffusion takes place faster?
b) Explain the reason based on the movement of particles.
c)How does temperature affect diffusion?
Answers
(a) an incense stick is burnt
(b) The main reason behind the movement of particles is the inter molecular forces and spaces between them.
(c) temperature affect diffusion because it increases the kinetic energy of the particles
Answer:
Diffusion takes place faster when an incence stick is burnt.
Explanation:
Diffusion: It is the process in which movement of particles takes place from one place to another or from one medium to other due to concentration gradient.
(a) Diffusion would be faster when an incense stick is burnt as compared to other cases given in question.
(b) Movement of particles takes place due to the concentration gradient. Particles move from a place of higher concentration towards the place of lower concentration.
(c) The rate of diffusion increases with the rise in temperature. Increase in temperature causes the increase in the movement of molecules which consequently, raises the rate of diffusion.
