In solids, molecules move randomly.

In the case of osmosis, solvent molecules move from :

In solids, the particles move about

As the temperature of a substance increases, its molecules move faster and thus the kinetic energy of the molecules increases.

In solid PCl_5 molecule, how many P-Cl bonds are present in the cation ?

Assertion: Though large number of free electron are present in the metal, yet there is no current in the absent of electric field. Reason: In the absence of electric field, electrons move randomly in all directions

Which is not correct in terms of kinetic theory of gases? a.Gaseous particles are considered as point mass. b.The gaseous molecules are in random motion. c.When gaseous molecules collide, they lose energy. d.When the gas is heated, the molecules moves faster.

In diffusion molecules move in (A)____ may be withdrawn from such regions and moved to the (B)____ to regions of (C)_____

In water each H_(2)O molecule is surrounded by y neighbouring H_(2)O molecules randomly by hydrogen bonding. Find the value of y.

Give reason On heating a sublimable solid, the molecules break free & escape from surface of the solid directly into vapour.

Assertion : Liquids and solids are hard to compress . Reason : Magnitude of the repulsive forces between the molecules rises very rapidly as the distance separating the molecules decreases .
