The ordinary refrigerator, when opening normally, has a temperature that approaches

Explanation:
The temperature inside a standard household refrigerator is kept near 4°C. This targets a sweet spot: cold enough to slow the growth of spoilage and pathogenic bacteria, but not so cold that foods begin to freeze and lose quality. If it were 0°C or colder, many items would start to freeze and textures could be damaged; at -4°C it would be a freezer, not a fridge. If it were as warm as 8°C, bacterial growth would proceed more quickly, increasing spoilage risk. When you open the door, the temperature can rise briefly due to warm room air, but the appliance’s thermostat cools back down toward about 4°C once the door is closed.
