Commune time to work ( physics) i need help pls :(

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

In what direction does an applied force move an object
