AIR PRESSURE IS THE FORCE EXERTED BY THE AIR

• -12

air pressure is exerted by air

1. Air exerts pressure- Suppose, we take a glass filled with water till it's brim and insert a cardboard piece in it's mouth and turn it upside down, we can see that the carboard piece does not fall off. This is because air exerts presure
2. Air expands on heating-In a hot air balloon when the air is heated the density of it becomes low and hence the volume of the air increases or expands
3. High speed wind is accompanied by low pressure- Suppose, we take a paper strip and hold it in our mouth and blow over it's top and we can see that the paper strip rises up. This is because when you blow air, a region of low pressure is created. Therefore, the air from the other sides will try push in and occupy this space of low pressure.

AIR EXERTS PRESSURE- PARACHUTE JUMPING,COOCKING PRESSURE AIR EXPANDS ON HEATING- WHEN A BURNIG CANDLE IS KEPT BELOW ANY ONE OF PAPER BAGS THAT IS TIED AROUND A STICK WILL DISTURB THIS IS BECAUSE THE AIR NEAR THE CANDLE GETS HEATED AND RISES UP .IT PUSHES THE BAG ABOVE

e.g. you fill air in cycle wheel to keep it tight , when you fill more of air it explode ( blast ) this tells that air exerts pressure
air expands on heating = hot air balloon

A Seabreeze describes as a wind blow from ocean inland towards land.

yes,air exerts pressure ...when you blow a balloon , blow off air inside it on a paper. the paper will blow away.this is how air exerts pressure.pressure exerted by air blow the paper away.

Sea Breeze is the mild to moderate wind blows from sea to land in the day.

Land being solid surface can easily absorb and release heat radiation. While sea being liquid heats up slowly and also loses this heat slowly. During the day time the sun heats up the land surface while the water body keeps on absorbing heat and is not hot yet. Land surface being hotter, hot air from land surface rises up creating a temporary low pressure zone which drags cool air from the sea to the land. Thus, we have the sea breeze.

Land Breeze is the mild to moderate wind blows from land to sea in the night.

As the day progresses and sun sets, the land loses heat quickly and the water body remains hot as it takes time to lose heat. During the night time, the land surface is cool as it loses its heat quickly. But the sea surface is still hotter as water bodies lose heat slowly. So, hot air from sea surface rises up and cool air from the land surface moves towards the sea. Thus, we have land breeze.
