Question

explain the working of manometer in detail



and I will mark as brainlist​

Answer 1

A manometer measures the difference in air or liquid pressure by comparing it to an outside source, usually a sample of Earth's atmosphere.

A U-shaped manometer essentially pits two different gas pressures against one another, and measures the strength of the captured gas.

A manometer is used to measure the pressure difference between two gases, often atmosphere and the gas being tested. A typical manometer consists of a U-shaped tube filled with either mercury or liquid. The long sides of the tube have a measuring scale marked off in millimeters.
