Welcome to this test on everyday science MCQs on air pressure. This test will help you learn about air pressure and how it works in our daily life. Air pressure is the weight of air around us. It affects many things, like why your ears pop when you go up a hill or how a straw works when you drink juice.
In this test, you will find simple everyday science MCQs on how air pressure works and its importance. For example, have you ever wondered why weather changes when air pressure changes? These questions will help you find the answers.
