Gas Pressure and its measurement

• The air in the high altitudes are is not compressed

• Because the amount of gas particles are decreasing due to less gravity

• Because the gas particles in high altitudes are less dense

• Because the gravity is increased at high altitude

101.3 kPa is equal to how many atm?

• 1

• 101325

• 760

• 14.7

If the pressure of a gas is measured to be 5 atm. What it will be in mm Hg?

• 380

• 3800

• 73.5
