Question

The protective barrier between a car's engine and the passenger compartment is referred to as a firewall. Judging by its location, this barrier principally serves what function?

Answer 1

The firewall in a car serves as a protective barrier that shields passengers from heat, noise, and potential fire hazards from the engine, similar to how a moat and castle walls defend against external threats.

Step-by-step explanation:

The protective barrier between a car's engine and the passenger compartment is known as a firewall. Its principal function is to protect the passengers from heat, noise, and potential fire hazards originating from the engine. In the event of an accident or engine malfunction, the firewall acts as a protective shield. The internal combustion engine in a vehicle is a source of high energy and can reach extremely high temperatures. In a collision, crumple zones are parts of a car that are designed to deform and crumple in a controlled way to absorb the energy of the impact, reducing the force transmitted to the occupants and thereby helping to protect them. This is similar to how a moat and castle walls protect the inhabitants from external threats, serving as the first line of defense.
