The temperature of the bullet and the wall play a crucial role in the melting process. At 27°C, the bullet may reach its melting point, causing it to melt upon impact with the wall.
The impact of the bullet with the wall causes friction and generates heat, which can raise the temperature of the bullet to its melting point. As a result, the bullet melts on the wall.
The length and weight of the bullet do not directly affect the melting process. However, a longer and heavier bullet may have more kinetic energy when it hits the wall, leading to a higher impact force and more friction, which can increase the temperature and cause melting.
Yes, it is possible for the bullet to remain solid after impact with the wall. The melting point of lead is 327.5°C, so if the bullet does not reach this temperature upon impact, it will not melt.
Yes, the temperature of the wall can affect the melting of the bullet. If the wall is at a higher temperature than the bullet, it can transfer heat to the bullet and raise its temperature, potentially causing it to melt. However, if the wall is at a lower temperature, it may not have a significant effect on the melting process.
