5. GAS LAWS AND SOLUTIONS

Question 1

Henry’s law is one of the
gas laws that states that

Answer 1

the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid

Question 2

Which chemical law proposes
that ‘soft drinks and soda bottles are
sealed under high pressure to increase
the solubility of CO₂ ’

Answer 2

Henry Law

Question 3

Who among the following
made the first observation on Platinum as a catalyst and discovered similar triads of elements that led to the
development of the periodic table ofelements

Answer 3

Johann Wolfgang Dobereiner

Question 4

Joule’s law states that

Answer 4

internal energy of an ideal gas depends only upon its temperature irrespective of volume and pressure

Question 5

Boyle’s law states that

Answer 5

the pressure of a gas is inversely proportional to the Volume.

Question 6

Avagadro’s law states that

Answer 6

equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

Question 7

Raoult’s law states that

Answer 7

for a solution of volatile liquids, the
partial vapour pressure of each
component of the solution is directly
proportional to its mole fraction
present in solution.

Question 8

Dalton’s law says

Answer 8

total pressure of mixture of gases is equal to the sum of partial pressure of individual gases.
