Final answer:
The 25 man life raft is inflated using compressed air or CO2, which is housed in a cylinder attached to the raft. The rapid inflation is critical for emergency situations, and the concept is related to physics principles such as pressure and buoyancy.
Step-by-step explanation:
The 25 man life raft is typically inflated using compressed air or CO2.
Modern life rafts come with inflation systems that may include a compressed air cylinder, very similar to those used by scuba divers. These cylinders contain compressed gas, which is quickly released into the life raft to inflate it when it is deployed. The life raft inflation process is designed to be rapid to ensure that in the case of an emergency, the raft can be made ready for use as quickly as possible.
Part of the inflation system may include a manual pump for topping off or fully inflating the raft if the automatic system fails or if additional pressure is needed. The question of the 25 man life raft inflation is related to understanding pressure and buoyancy, important concepts in physics. For example, understanding how much force is needed to create a certain pressure is similar to understanding how the life raft gets filled with air at a pressure that allows it to inflate rapidly and stay afloat.
