Measuring Gases

What does STP stand for?

Standard Temperature and Pressure (STP)

Temperature = 0^oC or 273 K

Pressure = 1atm , 760 mmHg, 101.3 kPa

​

​

What is Boyle’s Law

Boyle’s Law describes the inversely proportional relationship between the pressure and volume of a gas, if the temperature is kept constant within a closed system.

Boyles Law

Boyles equation: P₁V₁ = P₂V₂

​

Volume (L)

Pressure (kPa)

Watch the videos on google classroom.

• Work all the problems on each video on your notes.

​

• When you are done with the practice problems from the video, try the two practice problems on your own.

​

• Remember, you may use a calculator and a reference chart.

What is the new pressure of 300.0 ml of a gas that is compressed to 100.0 ml if its original pressure was 1140.0 mmHg and the temperature is held constant?

If you have a 200.0 ml container of compressed air in Galveston, where the pressure is 1.000 atm and then you get on a plane and fly to Denver, where the pressure is 0.750 atm, what will the new volume be?
