Q1: Flocculated particles do not change their

ANS:D - none of these.

1. Size: Flocculated particles do change their size. When particles flocculate, they come together to form larger aggregates or clusters, resulting in an increase in the overall size of the flocculated mass compared to the individual particles.
2. Shape: Flocculated particles may change their shape to some extent as they form aggregates, especially if they adhere to each other in specific orientations. Therefore, while the change in shape may not be drastic, it is not entirely accurate to say that flocculated particles do not change their shape.
3. Weight: The weight of flocculated particles increases as they aggregate and form larger clusters. This is because the total mass of the particles combined increases due to flocculation.
