Define (i)Molecule (ii)Force of cohesion (iii)Diffusion (iv) Kinetic theroy of matter
Answers
Explanation:
(I) A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.
(ii) Cohesion or cohesive attraction or cohesive force is the action or property of like molecules sticking together, being mutually attractive.
(iii) Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.
(iv) The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. ... Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
