The downward pressure on the hg in barometer is ______ the pressure of the atmosphere.
enyata [817]

The downward pressure on the hg in barometer is <u>the same as</u> the pressure of the atmosphere.

The atmospheric pressure or barometric pressure is the force exerted by the air in the atmosphere on the earth's surface.

The atmospheric pressure is caused by air molecules colliding with the surface. The atmospheric pressure at sea level is about 101 kPa and at the cruising altitude of a passenger plane it is 27 kPa.

The atmospheric pressure decrease as the height of a surface above ground level increases.

<h3>What is a barometer?</h3>

A barometer is a measuring instrument used to measure the atmospheric pressure or weight of the air, which is useful for making weather predictions.
