Q:

Two cubes have their volumes in the ratio 1 : 27. Find the ratio of their surface areas.

A) 2:9	B) 3:9
C) 1:9	D) 4:9

Answer & Explanation Answer: C) 1:9

Explanation:

Let their edges be a and b. Then,

a3/b3 = 1/27 (or) (a/b)3 = (1/3)3 (or) (a/b) = (1/3).

\Ratio of their surface area = 6a2/6b2 = a2/b2 = (a/b)2 = 1/9, i.e. 1:9.

Pieces of camphor placed on water move about rapidly. This is because of

A) diffusion	B) viscosity
C) surface tension	D) capillarity

Answer & Explanation Answer: C) surface tension

Explanation:

The Camphor slowly dissolves in the water lowering the latter's surface tension in the immediate neighbourhood. The stronger pull exerted by the uncontaminated portion of water brings about a movement of the surface and the camphor particles are carried along with it. When after sometime the whole surface settles for the reduced tension, the movement of the camphor too short.
