How do fridges help us in our everyday lives?

Fridges play a crucial role in our everyday lives by preserving food and beverages, which helps reduce waste and saves money. They maintain a consistent, cool temperature that slows down bacterial growth, ensuring food safety and extending shelf life. Additionally, fridges allow for convenient meal planning and storage, making it easier to access fresh ingredients and leftovers. This efficiency not only supports healthier eating habits but also enhances overall quality of life.


Why do you check the temperatures of fridges and freezers?

It is a safety issue. Food needs to be taken care of and stored at certain temperatures to prevent the growth of bacteria in the food. The way to be sure that this is happening is to take readings on a regular basis.


Why does Scott base still need fridges and freezers in such a cold place?

Scott Base, located in Antarctica, still requires fridges and freezers to store perishable food and other temperature-sensitive supplies, even in such a cold environment. The interior of the base can be heated for comfort and operational purposes, which means that food could spoil if not properly stored. Additionally, maintaining specific temperatures is essential for preserving the quality and safety of certain items, especially those that require precise conditions that the ambient temperature alone cannot provide.


How does volume affect temperature?

Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.
