15.4 Steam at 100°C is injected into 1.8 kg of water at 22°C in a well-insulated container, where it condenses and mixes with th ...

19.0 - Introduction We live in a vast ocean of gas called the atmosphere. Deeper than the seas, it provides the oxygen we breath ...

Using descriptions like “large” and “frequently” does not convey the nature of gases as well as specific numbers. Consider nitro ...

19.3 - Boyle’s and Charles’ gas laws In this section we take a macroscopic view of ideal gases to discuss their overall properti ...

0.020 m^3 of gas expands to 0.040 m^3. Its initial pressure was 5.0×10^5 Pa. Assume its temperature is constant. What is its fin ...

much mass as a mole of Carbon-12. The mass per mole of a substance is called its molar mass. When measured in grams (or, to be p ...

What is the volume of one mole of gas at standard temperature and pressure? Standard temperature is 273 K and standard pressure ...

to one another. Set them equal to each other in an equation. Solve for the final temperature and evaluate. Physics principles ...

19.8 - Interactive checkpoint: volume of an ideal gas A quantity of an ideal gas occupies a volume of 2.18 m^3 at 288 K, with an ...

Internal energy, ideal monatomic gas Eint = internal energy of gas n = amount of gas in moles R = gas constant Two moles of an i ...

19.10 - Gotchas Using the wrong temperature scale. Make sure you use Kelvin, not Celsius (and certainly not Fahrenheit!), when a ...

Chapter Assumptions Use the following values for constants: NA = 6.02×10^23 R = 8.31 J/mol·K k = 1.38×10–23 J/K. In problems whi ...

Section 4 - Avogadro’s number and moles 4.1 How many molecules are there in 0.017 moles of carbon dioxide gas, CO 2? molecules 4 ...

5.7 A quantity of an ideal gas is held in a cylinder with a movable piston. At a temperature of 245°C, the gas has a volume of 0 ...

20.0 - Introduction The desire to build more powerful and efficient engines led engineers and scientists to embark on pioneering ...

It is important to define what we mean by “system.” Here we define the system as the engine that includes the container, with it ...

amount of work done by the paddles, was always proportional to the increase in the temperature of the water. This proved a relat ...

You see this stated as an equation to the right. The net work done by the engine during a cycle equals the heat transferred into ...

The engine piston is locked in position and heat flows into the gas. What happens to the pressure, volume, and temperature? Volu ...

Second process. Now, we release the lock on the piston. This allows the gas to expand, doing work by moving the piston. The inte ...
