Question

DIRECTION In the following questions, a statement of assertion (A) is followed by a
statement of reason (R) Mark the correct choice as
(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of
assertion (A)
(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of
assertion (A)
(c) Assertion (A) is true but reason (R) is false,
(d) Assertion (A) is false but reason (R) is true,

A. Assertion: Solids do not diffuse in air,
Reason: The particles are closely packed in solids

B. Assertion: The rate of evaporation increases with increase in temperature,
Reason: Increase in temperature increases the kinetic energy of the particles​

Answer 1

Answer:

1) Both A and R are true

2)Both A and R are true

Explanation:

1)Solids cannot diffuse each other because they are tightly packed and they are rigid. Solid particles are closely and tightly packed around each other that they cannot move to diffuse into one another.

2) The water molecules move rapidly when the water is heated. This makes the molecules escape faster. It also increases the kinetic energy of the molecules.
