2. Lemon sherbat has sweet,sour and salty taste and it can be poured in a glass.

3. A solid matter has the properties of definite shape and volume.

Answer 1

1.Constituent particles of a colloid have very small size as compare to the pores or holes of filter paper.

This means that filtering any colloid with filter paper will allow the colloid particle to pass through it and thus no residue is left.
