The gas laws and their principles govern the behavior of... Show more
This section explores two fundamental gas laws in chemistry: Boyle's Law and Dalton's Law of Partial Pressures.
Boyle's Law states that gas volume is inversely proportional to the pressure applied when temperature and moles are constant. The mathematical expression is P₁V₁ = P₂V₂.
Example: If 100 mL of oxygen under 150 kPa is put under a greater pressure of 200 kPa, the new volume will be 75.0 mL.
Dalton's Law of Partial Pressures states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases, assuming constant volume and temperature.
Formula: Pₜₒₜₐₗ = P₁ + P₂ + P₃ + ...
Example: In a mixture where Pₙ₂ = 79.10 kPa, Pₐᵣ = 0.040 kPa, and Pₒₜₕₑᵣₛ = 0.94 kPa, with a total pressure of 101.3 kPa, the partial pressure of oxygen would be 21.2 kPa.
Highlight: When collecting gas bubbles through water, the pressure of water vapor must be included in calculations using Dalton's Law.
This section covers two more important gas laws in chemistry: Charles' Law and Gay-Lussac's Law.
Charles' Law states that the volume of a gas is directly proportional to temperature when pressure and number of moles are constant. The mathematical expression is V₁/T₁ = V₂/T₂.
Highlight: Temperature must be expressed in Kelvin for gas law calculations to ensure a direct proportion and avoid negative values.
Vocabulary:
- Absolute zero: The lowest possible temperature where all molecular motion theoretically stops.
Example: A sample of helium occupying 473 cm³ at 36°C will have a volume of 562 cm³ when the temperature is increased to 94°C.
Gay-Lussac's Law states that when volume and moles are kept constant, pressure and temperature are directly proportional.
The Combined Gas Law incorporates Boyle's, Charles', and Gay-Lussac's laws into a single equation: P₁V₁/T₁ = P₂V₂/T₂.
Example: A gas with a volume of 7.84 mL at 11.8 kPa and 25.0°C will have a volume of 5.09 mL at STP .
This section introduces Avogadro's Law and the concept of molar volume in gas chemistry.
Avogadro's Law states that pressure and the number of gas particles are directly proportional when temperature and volume are constant.
Molar Volume is a crucial concept in gas stoichiometry:
Formula: 1 mol = 22.4 L
This principle allows for interrelation of mass, moles, pressure, volume, and temperature for any gas sample.
Example:
- A flask containing 19.0 L of O₂ at STP: a. Contains 0.848 mol of O₂ b. Has a mass of 27.1 g of O₂ c. If it were H₂ instead, it would have a mass of 1.71 g
- A 15.0 L flask containing 12.5 g of unknown gas at STP has a molecular mass of 18.7 g/mol
This section applies gas laws and molar volume concepts to stoichiometric calculations in chemistry.
In gas stoichiometry, volume can be used similarly to moles in calculations.
Example:
- In the reaction 2H₂ + O₂ → 2H₂O: If we start with 2 L of H₂, we will produce 2 L of H₂O and consume 1 L of O₂.
- In the reaction 3KNO₃ + Ag₃PO₄ → 3AgNO₃ + K₃PO₄: If 3.4 mL of K₃PO₄ is produced, the reaction started with 10 mL of KNO₃.
These examples demonstrate how gas laws and stoichiometry can be combined to solve complex chemistry problems involving gases.
This final section introduces the Ideal Gas Law and the underlying Kinetic Molecular Theory in gas chemistry.
The Kinetic Molecular Theory provides assumptions that all gas laws follow, describing an "ideal gas":
Definition: An ideal gas is a theoretical gas composed of randomly moving particles that do not interact except through brief elastic collisions.
The Ideal Gas Law combines all previously discussed gas laws into a single equation: PV = nRT
Where:
Highlight: While the Ideal Gas Law is based on theoretical assumptions, it provides a good approximation for the behavior of real gases under many conditions, especially at low pressures and high temperatures.
This comprehensive overview of gas laws and their applications provides a solid foundation for understanding the behavior of gases in Grade 10 chemistry and beyond.
This page introduces the Ideal Gas Law and the Kinetic Molecular Theory, which provide a theoretical framework for understanding gas behavior.
The Ideal Gas Law is a combination of all previously discussed gas laws and is expressed as:
PV = nRT
Where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin.
Definition: Ideal Gas Law - An equation of state for a hypothetical ideal gas, combining multiple gas laws into a single formula.
The Kinetic Molecular Theory provides assumptions that underlie the behavior of an "ideal gas":
Highlight: While real gases deviate from ideal behavior, the Ideal Gas Law and Kinetic Molecular Theory provide valuable approximations for many gas-related calculations.
Understanding these concepts is essential for advanced study of gas behavior in physics and chemistry.
This page focuses on practical applications of gas laws and problem-solving techniques.
The page emphasizes the importance of unit conversions and proper use of formulas when solving gas-related problems. It also highlights the significance of understanding the relationships between pressure, volume, temperature, and number of moles in various gas law scenarios.
Highlight: Proficiency in applying gas laws to real-world situations is crucial for success in physics and chemistry courses, as well as in many scientific and engineering fields.
The page provides additional examples and practice problems to reinforce understanding of gas law concepts:
Example: Calculating the molecular mass of an unknown gas using the Ideal Gas Law: A 15.0 L flask contains 12.5 g of unknown gas at STP. First, find the number of moles using the molar volume concept: 15.0 L × = 0.670 mol. Then, calculate the molecular mass: 12.5 g / 0.670 mol = 18.7 g/mol.
These practical applications demonstrate the wide-ranging utility of gas laws in scientific problem-solving and analysis.
Mole Fractions and Partial Pressures
This section explains how to calculate partial pressures and mole fractions in gas mixtures.
Formula: Mole fraction = moles of gas/total moles
Example: Calculations involving hydrogen and helium mixtures demonstrate partial pressure determination.
This section introduces fundamental concepts related to gases in chemistry, focusing on pressure and standard conditions.
Pressure in gases is defined as the force per unit area exerted by gas particles on the walls of their container. The kinetic molecular energy of gas particles causes constant motion, resulting in collisions with container walls and creating pressure.
Highlight: Gases can be compressed to fit in smaller containers due to the space between particles.
Standard Temperature and Pressure conditions are crucial reference points in gas chemistry:
Example: Converting pressure units:
- 75.0 kPa = 0.740 atm
- 2315.1 Pa = 17.3 torr
Vocabulary:
- Kinetic molecular energy: The energy possessed by gas particles due to their motion.
- STP: Standard Temperature and Pressure, used as a reference point in gas chemistry calculations.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
