Answers
Answer:
(a) water>air>wind
(b) sugar>oil>air
(c) iron>water>oxygen
(d) salt>juice>air
Explanation:
Force of attraction depends upon the number of molecules inside the matter. Force of attraction is most in solid, intermediate in liquid and least in gases.
Answer:
Intermolecular forces are forces of attraction or repulsion which act between neighbouring particles (atoms,moleculesorions). These force keep a molecule together.
In solid, a particle can vibrate but they can not move. Sugar is solid.
In liquid, the force of attraction is weaker than solid. Water is a liquid.
In gas, the particle moves fast in a random direction so there is no force of attraction. Oxygen is a gas.
Oxygen,water,sugar is the increasing order of forces of attraction.
Option C is correct.
