What happens to a 25 Watt light bulb in a fire?

In a fire, a 25 Watt light bulb typically experiences a reduction in pressure as the heat from the fire causes the glass to expand. However, the heat also affects the internal pressure of the bulb, which can lead to a phenomenon known as implosion. In this scenario, as the glass heats up unevenly, parts of the bulb can contract while other areas expand. The glass may pull inward instead of maintaining its shape. This pulling inward is often facilitated by the changes in internal gas pressure in response to extreme heat, resulting in a more collapsed structure.

The correct answer reflects the physical dynamics occurring in response to intense heat during a fire, which can lead to the bulb's glass being pulled inward rather than remaining stable or shattering outward.
