How cold is the baggage compartment on a plane and what measures are taken to ensure the safety of items stored there?

The baggage compartment on a plane is typically kept at temperatures around 7 to 20 degrees Celsius. To ensure the safety of items stored there, airlines use insulation and heating systems to regulate the temperature and prevent extreme cold or heat from damaging the items. Additionally, items are securely packed and handled to prevent damage during loading and unloading.
