Fill in the blanks.
The volume of a solid can be measured by the method of displacement, where the solid is _____ in water and the _____ in water level is measured.
immersed (or lowered); rise (or increase)
The maximum amount of _____ dissolved in _____ at a particular temperature is called solubility at that temperature.
solute; solvent (or solution)
Generally, the density _____ with increase in temperature.
decreases
The solution in which glucose has completely dissolved in water, and no more glucose can dissolve at a given temperature, is called a _____ solution of glucose.
saturated
Explanation
(i) Activity 9.7 on Page 13 describes this method: 'Tie the object, say a stone, with a thread and slowly lower it into the measuring cylinder... Subtract the initial volume from the final volume after the object is put into the measuring cylinder. This is the volume of the object.' (ii) The chapter defines solubility on Page 4: 'the maximum amount of solute that dissolves in a fixed quantity of the solvent is called its solubility.' (iii) Section 9.5.2 on Page 14 states: 'Generally, the density of a substance decreases with heating... As temperature increases, the particles of a substance... tend to move away and spread. This results in an increase in volume but there is no change in mass.' (iv) The chapter defines on Page 4: 'when the solute stops dissolving and begins to settle at the bottom, the solution is called a saturated solution at that particular temperature.'
