Answer 2

Answer:

Water is the bad conductor of heat then to it is hot on heating because the molecules move and heated

Explanation:

Experiments

Material required

A large potassium permanganate crystal, a beaker, a burner and water

procedure

1. drop the potassium permanganate crystal into the beaker containing a little water the Crystal start dissolve in a water and colour it

2. now pour some more water slowly into the beaker without disturbing the Crystal

3. heat water using a very small flame just below the Crystal

observation

the coloured water rises from the place where the heat is supplied after moving up some distance it spread out and comes down along the side of a beaker
