Gas Pressure Unit Conversion Mastery

This video tutorial explains how to convert between different units of pressure, such as atm, torr, kilopascals, and psi. It covers the basic definitions and relationships between these units, provides step-by-step examples of conversions, and discusses the application of these conversions in real-world scenarios like measuring tire pressure and atmospheric pressure using a barometer.

Which of the following is equivalent to 1 atm?

• 101.3 psi

• 760 kilopascals

• 14.7 torr

• 101.3 kilopascals

What is the standard unit of pressure in physics?

• psi

• pascals

• torr

• atm

How many pascals are in one kilopascal?

• 10000

• 10

• 1000

• 100

What is the pressure of a gas in atm if it is 725 torr?

• 0.9539 atm

• 1.2 atm

• 1.5 atm

• 0.8 atm

If the tire pressure of a car is 32 psi, what is it in atm?

• 2.5 atm

• 3.0 atm

• 1.5 atm

• 2.177 atm

What is the height of the mercury column in a barometer if the pressure is 0.843 atm?

• 640.68 mm

• 760 mm

• 800 mm

• 700 mm

What is the pressure of the air at a certain valley below sea level if it is 117 kilopascals?

• 760 mm Hg

• 877.8 mm Hg

• 900 mm Hg

• 800 mm Hg

What is the conversion factor between psi and torr?

• 1 psi = 760 torr

• 14.7 psi = 1 atm = 760 torr

• 14.7 psi = 101.3 torr

• 1 psi = 101.3 torr

How do you convert 50 psi to units of torr?

• 50 / 14.7 * 760

• 50 * 14.7 / 760

• 50 / 760 * 14.7

• 50 * 760 / 14.7

What is the pressure in torr if the air pressure inside the tires of a truck is 50 psi?

• 1500 torr

• 2585 torr

• 3000 torr

• 2000 torr
