Answer:

The pressure of the gas inside the apparatus is 1000 mmHg

Explanation:

Given;

outside pressure, Patm = 750 mmHg

change in height of the two columns, Δh = 25 cm = 250 mm

The pressure of the gas inside the apparatus is given by;

P(gas) = P(atm) + P(Hg)

where;

P(atm) is the outside pressure

P(Hg) is the gauge pressure = height difference of the two columns.

P(gas) = 750 mmHg + 250 mmHg

P(gas) = 1000 mmHg

Therefore, the pressure of the gas inside the apparatus is 1000 mmHg

The pressure of the gas inside the apparatus is 1000 mmHg.

Since

outside pressure, Patm = 750 mmHg

change in height of the two columns, Δh = 25 cm = 250 mm

so we know that

The pressure of the gas inside the apparatus is

P(gas) = P(atm) + P(Hg)

here;

P(atm) is the outside pressure

P(Hg) is the gauge pressure = height difference of the two columns.

So,

P(gas) = 750 mmHg + 250 mmHg

P(gas) = 1000 mmHg
