Answers
Answer:
Ans1- Homogeneous
Ans2- solvent
Ans3- heterogeneous
Ans4- sugar solution
Ans5- water
Ans6- False, because When a solute is added to a solvent, the kinetic energy of the solvent molecules generally overcomes the attractive forces among solute particles. However, as the temperature increases, the solubility of a gas in a liquid decreases.
Ans7- False, because A given quantity of solute dissolves faster when it is ground into small particles than if it is in the form of a large chunk because more surface area is exposed.
Ans8- false because, Stirring affects how quickly a solute dissolves in a solvent, but has no effect on how much solute will dissolve. The amount of solute that will dissolve is affected by temperature - more will dissolve at higher temperatures. This is called the solubility of the solute .
Ans 9- true
Ans10- false , as Oil is not soluble in water.
Ans 12-
