Question

The volume of an air bubble is doubled as it rises from the bottom of lake to its surface the atmospheric pressure is 75 cm of mercury the ratio of density of mercury to that of lake water is 43 the depth of the lake in metre is

Answer 1

Explanation:

Reduced gas flow rates through the sampling chamber due to increased difficulty encountered by the pump as a result of decreased density of the gases at lower pressures. 2. The second explanation for malfunction of the instrument is the effect of low barometric pressure on calibration.

This increase in energy is an increase in pressure. If you reverse the process and cool down a gas, the pressure decreases as well. Atmospheric pressure is a large component of how weather works. As air moves around the globe, pockets of high pressure and low pressure build up.
