Text Solution

AI Generated Solution

To explain why the mercury level in a barometer goes down when atmospheric pressure decreases, we can break down the explanation into a series of logical steps: ### Step-by-Step Solution: 1. **Understanding the Barometer**: A barometer is a device used to measure atmospheric pressure. It typically consists of a glass tube filled with mercury, inverted in a reservoir of mercury. 2. **Role of Atmospheric Pressure**: The atmospheric pressure is the force exerted by the weight of air molecules in the atmosphere. This pressure acts on the surface of the mercury in the reservoir. ...
