ᴇxᴩʟᴀɴᴀᴛɪᴏɴ:

In all, there is just a temporary rise in temperature and release energy in the form of light. When we switch the bulb off, these things go back to normal in some period of time. Hence, glowing of a bulb is a physical type of change.

Answer 2

Physical changes include changes in the state of matter, changes in solubility, colour, and odour.

Explanation:

• When a substance experiences a physical change, its composition or chemical makeup does not change.
• Simply said, the molecules rearrange themselves somewhat without changing their internal structure or content.
• When we turn on a light bulb, electrons in the tungsten wire are stimulated, and energy is released in the form of photons.
• Overall, there is only a brief increase in temperature and energy release in the form of light. When we turn off the light, these things return to normal after a while.
• As a result, the glowing of a bulb is a physical change.
