Question

is holding a temperature probe in the fridge an example of convection? Why?

Answer 1

Yes. Holding a temperature probe in the fridge is an example of convection. The prcocess by which a fridge removes heat from the freezer and refrigeration compartments and disposes of it outside unit relies on the concept of convection. Convection is a process of heat transfer throught the movement of matter, usually a gas or a liquid. In the case of the frodge, convection occurs through the use of refrigerant gases and a compressor.

Fridge operate usingconvection by circulating the gas through the copper lines inside the freezer compartment. The lines, and the gas contained within them, absorb the heat contained in the fridge and freezer compartment and are circulated back outside of the unit. The unit then compresses the refrigerant gas, using a compressor, outside the fridge. As the gas is compressed, it discharges the heat it absorbed inside of the food compartments into the room.
