Question

What happens when we burn a wet cloth?

Answer 1

Answer:-

Materials Required:-

1. Wet Cloth
2. Burner
3. Grill
4. Fuel

Process:-

• Take a wet cloth.
• Place it on a burner. (Note: It is very risky to have such activities. Adult Supervision required. Be assured that between the burner and the cloth a metal grill should be there.)
• After some time, we will notice that the water particles present in the wet cloth, soon get turned into vapour (Vapourised).
• The vapour moves up in the atmosphere.
• Then, the wet cloth becomes dry and it burns. (Note: This is stage is very dangerous.)

Note: The burner should work only when fuel is provided to it.

REQUIRED ANSWER:

When we burn a wet cloth, after some time, the water particles turn into vapour and move up in the atmosphere. Then, it becomes dry and combustion takes place. Then, after complete combustion, it becomes ash.

Answer 2

Answer:

• The heat which is supplied to burn a etc cloth first is consumed to evaporate the water in cloth for which the cloth remains unburnt.
• then slowly the cloth reaches its ignition temperature and catches fire. thus the process of burning wet cloth is rather slow than to burn a dry cloth which catches fire very quickly.
