Concept of Pressure, Explanation and Important Questions
Correct Option: (b) Explanation: Since, Pressure (P) = Force (F)/Area (A) Hence, we can conclude from the above equation that pressure is inversely proportional to area. So, if the area decreases, the pressure increases. 2) The decrease in pressure takes place when _____>. a) The force is increased but not the area.

How Do Pressure Cookers Work? The Science Behind Them …
Pressure cookers are a convenient kitchen appliance used to cook food quickly with the power of steam pressure. Even without pressure steam conducts heat and cooks faster than dry air, but with increased pressure, the steam can rise above its usual maximum temperature and cook even faster. These factors make steam pressure …

Pressure Systems – High Pressure System, Low Pressure …
A pressure system is an area of the Earth's atmosphere that has a particularly high or low pressure compared to the surrounding air. We live at the bottom of the atmosphere, and the weight of all the air above us is known as air pressure. Pressure varies from day to day at the Earth's surface because the earth is not equally heated by the sun.

What is high pressure?
A high-pressure area is a region where the atmospheric pressure at the surface of the Earth is greater than its surrounding environment. Areas with above-average pressure are called anticyclones. Anticyclones occur when air is sinking. As a result, there are usually very few clouds in the air. In the UK, anticyclones bring cold clear days in ...
