What is the primary consequence of increasing the mass of the Phase Change Material (PCM) used in the baby incubator?

It decreases both the safety duration and the time needed to recharge the device.

It increases the safety duration but also increases the time required to recharge it.

It makes the incubator lighter and easier to transport between different clinic rooms.

It reduces the recharge time while having no effect on the safety duration for the baby.

An engineer designs an incubator with an extremely large mass of PCM, providing a very long safety duration. What is the most likely drawback of this design for a busy rural clinic?

The incubator will become excessively heavy, making it difficult for staff to move and creating a potential safety hazard.

The device will become too hot for the baby during its initial operation.

The long time needed to melt the PCM will limit how often the incubator can be used.

The materials will degrade quickly, requiring frequent replacement of the PCM.

An increase in the incubator's total weight.

A reduction in the safety duration.

A more complex and difficult recharging process.

A higher operating temperature for the device.

A longer safety duration is a key marketing feature for the product.

It is the easiest engineering variable to measure and control during testing.

The fundamental purpose of the device is to keep the baby warm and safe.

A shorter safety duration would require using much more expensive materials.

The type of insulation used in the incubator's outer shell.

The mass of the Phase Change Material inside the unit.

The alarm system that indicates temperature changes.

The color and external appearance of the incubator.
