Q1. Real gases show deviations from ideal gas law because
Answer : Option D
Explaination / Solution:
Real gases have intermolecular forces of interaction due to which there is a difference in the actual pressure values when compared to the ideal gases, the pressure is found to be less than the pressure of ideal gases under similar conditions, similar deviation occurs when the size of molecules is taken into account due to which volume correction is required.
Q2. For reactions involving gases, however, it is usually more convenient to express the equilibrium constant in terms of

Answer : Option C
Explaination / Solution:
Growth is defined as a permanent or irreversible increase in dry weight, size, mass or volume of a cell, organ or organism. Growth in living beings is intrinsic or internal.
Q6. Which of these statements about De Broglie Explanation of Bohr model is correct?
Answer : Option C
Explaination / Solution:
No Explaination.
Q7. The number of species that are known and described is
Answer : Option A
Explaination / Solution:
Each different kind of plant, animal or organism represents a species. The number of species known and described ranges between 1.7-1.8 million. This refers to biodiversity or the number and types of organisms present on earth. Hence, the correct option is 1.7 – 1.8 million.
Q8. Water hyacinth is called as terror of Bengal due to
Answer : Option C
Explaination / Solution:
Water hyacinth is water weeds which grows very fast and covers the whole ponds in few days. Weeds absorb oxygen from the water and make it oxygen deficient that kills the fish in ponds along with other aquatic organisms.
