why is heat transfer by convection possible only in liquid and gases how are land and sea breeze caused
Answers
Hey mate here is your answer:-
Convection is a type of heat transfer that can only happen in liquids and gases, because it involves those liquids or gases physically moving.
Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks. But let's use an example to think about why it happens, lest we assume that the fluid has a mind of its own.
The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.
This process also works in reverse at night. Only this time it is known as the land breeze. The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind.
