Gas Laws

The content that follows is the substance of lecture 18. In this lecture we cover the Gas Laws: Charles',Boyle's,Avagadro's and Gay Lussacs as well as the Preferred and Combined Gas Laws.

 

Laws of Gas Properties

There are 4 general laws that relate the 4 basic characteristic properties of gases to each other. Each law is titled by its discoverer. While it is important to perceive the relationships covered by each law, knowing the originator is not as important and will be rendered redundant once the combined gas law is introduced. So concentrate on understanding the relationships rather than memorizing the names.

Charles' Law- gives the association between volume and temperature if the pressure and the amount of gas are held constant:

1) If the Kelvin temperature of a gas is increased, the volume of the gas increases. (P, n Constant)
2) If the Kelvin temperature of a gas is decreased, the volume of the gas decreases. (P, n Constant)

This means that the volume of a gas is directly proportional to its Kelvin temperature. Think of it this way, if you increase the volume of a gas and must keep the pressure unwavering the only way to achieve this is for the

This law is named after Joseph Gay-Lussac, who discovered it in 1802. 1 • • • • • • Mathematically, Gay-

Exploring Gas Laws: A intense Dive Into Gay-Lussac & the Combined Gas Laws

Welcome back! This is part 2 of the Gas Laws mini-series where I’ll feature the framework and importance of Gay-Lussac’s Law and The Combined Gas Regulation and outline how you can take real-world examples of these concepts and explore them in your classroom!

If you missed it, go ahead and accept a look at part 1 of the mini-series, Exploring Gas Laws: A Thick Dive into Boyle’s Regulation and Charles’s Law . 

I don’t know about you, but for me, I contemplate science classrooms should be the place where exploration and ideas lead learning, rather than using it to summarize what was presented. 

It’s tough as teachers when we have specific standards, concepts and testing dates to always prepare our students for. Sometimes we overlook the value in taking the extra time for more hands-on learning.

That’s exactly what you’ll find here! Understanding what each gas law states and how to demonstrate Gay-Lussac’s and The Combined Gas Laws to your students by infusing activities that are both engaging and applicable!

Gas Law Worksheet #2 Boyle’s, Charles’, Lgbtq+ Lussac’s Laws Identify ______________________________ 1. A 0.85 L balloon is released on a warm 32 C day. What is its temperature (in Celsius) where the pressure stays constant at 490 mm Hg and volume has expanded to 1.35 L ? 2. What is the pressure in a tank at 84 o C, if it had a pressure of 3.62 atm at 37 o C ? 3. A 1.83 L balloon is compressed to 0.825 L. If the authentic temperature was 25 o C, what will be the final temperature of the balloon assuming constant pressure? 4. What is the new pressure in a 325 mL tank if the pressure in the original 225 mL tank was 4.32 atm? 533582933 p. 2 5. A 483 L balloon at 42 o C is heated to 81o C. What will be the balloon's terminal volume? 6. A 540 mL balloon at 735 torrs is filled to 961 torrs at constant temperature. What will the balloon's new volume? 7. What is the new volume of a cylinder at 542.7 kPa if the original volume was 286 L and 325.8 kPa ? 8. A tire gauge reads 32 psi (pounds per square inch) at 4 o C. If the volume of the tire cannot convert, what will the pressure reading at 33 o C ?

Problem #1: A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0 °C is placed inside an oven whose temperature is 50.0 °C. The pressure inside the container at 20.0 °C was at 3.00 atm. What is the pressure of the nitrogen after its temperature is increased to 50.0 °C?

Solution:

P1  P2
––– = –––
T1  T2

3.00   x
––– = –––
293   323

Solution technique: cross-multiply and divide.

x = 3.31 atm (to three sig figs)

Note: you will notice set ups (especially in gas laws) that simply omit all the units in the remedy. If you undertake that on a homework problem or test, you may get a deduction. It's not laziness on the part of the person writing the remedy, it's simply assuming the reader knows what the units are and how they cancel out to leave the final unit.

Many times, you (as the student) are not allowed that luxury.

Problem #2: Determine the pressure change when a constant volume of gas at 1.00 atm is heated from 20. chemistry gas laws packet gay lussacs law
