Q4. The rate at which a solid dissolves in liquid does not depend on
Answer : Option B
Explaination / Solution:
The rate at which a solid dissolves in liquid does not depend on pressure.
Q5. Solubility of gas decreases with
Answer : Option C
Explaination / Solution:
Because of increase in kinetic energy of gas molecules with temperature there tendency to escape from the liquid will increase.
