Question

What are the changes that can occur when matter is heated? Explain with

examples.​

Answer 1

Answer:

The change from solid to liquid is called melting or fusion. When a liquid is steadily heated, the particles move rapidly until many of them have sufficient energy to escape from the liquid and form a gas. This change of state is called evaporation. The liquid can also be changed to the solid state.

QUESTION :

• What are the changes that can occur when matter is heated? Explain with examples.

ANSWER :

EXAMPLES :

• dew to heating effect of heating solid change into liquid and easy to . vapour ,and dew to heat we get warm during winter season dew to heater work on principle of heating effect of electric current.

• When a liquid is steadily heated, the particles move rapidly until many of them have sufficient energy to escape from the liquid and form a gas. This change of state is called evaporation. The liquid can also be changed to the solid state.
