Question

When air pressure increases the liquid in a mercury barometer?

Answer 1

It forces the mercury to rise, being pushed up the tube by pressing down on the dish.

I hope I could help :)

Answer 2

rises

Step-by-step explanation:

The pressure depends on the height of mercury column raised. It is given by the formula

P = h d g

where, h is the height of mercury, d be the density of mercury and g be the value of acceleration due to gravity.

The density of mercury is constant and the value of acceleration due to gravity is constant, so as the pressure increases the value of height also increases. Thus, the height of liquid in the mercury barometer rises.
