Where will it take more time to cook rice?
(A) on the beach
(B) in Shimla
(C) Mount Everest
(D) at the depth of the sea

What happens to the temperature of a liquid when it evaporates?
(A) increase
(B) remain unchanged
(C) grow faster
(D) decrease
Correct Answer : D
Explanation :
During the process of evaporation of liquid the temperature of the liquid decreases because the surface molecules while evaporating take some amount of energy from the other molecules of liquid. Thus, evaporation leads to cooling. Kinetic energy is proportional to absolute temperature.
The reason for the diffusion of light in the atmosphere is?
(A) Carbon dioxide
(B) Water Vapor
(C) Helium
(D) Dust Particles
Correct Answer : D
Explanation :
The correct answer is dust particles. Diffusion of light in the atmosphere takes place due to dust particles. Diffusion is the net fluctuation of anything (for example, atoms, ions, molecules, energy) from a region of higher concentration to a region of lower concentration.
If a cell is placed in a solution and the net effect is that the cell begins to swell, then it is a solution.
(A) Hypertonic solution
(B) Isotonic solution
(C) Hypotonic solution
(D) Acidic solution
