• A. In the beaker containing cold water, ink spreads slowly.
• B. In the beaker containing hot water, ink spreads faster.
• C. The spreading of ink takes place due to the movement of water molecules.
• D. Ink will not dissolve.

Answer 1

Answer: (A), (B), (C)

The correct options are
A In the beaker containing cold water, ink spreads slowly.
B In the beaker containing hot water, ink spreads faster.
C The spreading of ink takes place due to the movement of water molecules.

When we put a drop of ink to each of the beakers the spreading of ink takes place due to the movement of water molecules.
In the beaker containing cold water, the ink spreads slowly and in the beaker containing hot water, the ink spreads faster because the movement of water molecules in hot water is faster than the cold water.
