Observe the changes and record your observations in the table. S.No. Material added Dissolves (Yes/No) 1 Example : Sugar Yes 2 Salt 3 Sand 4 Saw dust 5 Chalkpowder​

Answer 1

Changes observed when given quantities taken in a beaker with water.

Explanation:

• When the first quantity i.e. sugar is taken in a separate beaker with water than it get dissolved in water as it is soluble in water.
• When the second quantity i.e. salt is taken in a beaker with water than it also get dissolved in water because it is also soluble in water just like sugar.
• When the third quantity i.e. chalk powder is taken with water in a beaker than it does not dissolved in water as it is not soluble quantity.
• When the fourth quantity i.e. sand is taken with water in a beaker than it also does not dissolved in water because it is not soluble in water.
• Now when the last quantity i.e. saw dust is taken in a beaker with water, it also does not dissolved in water because it is also not soluble in water.
