According to Charles’s law, the volume of a gas is directly related to its temperature in kelvins at constant pressure and the number of moles. In your initial post to the discussion, respond to the following prompts: What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different? How would this change our day-to-day lives? Pick one of the following questions and try to answer it using one of the laws you learned in this module: How do spray cans work? Why do you need to fill up your tires with air on a cold day? Why do soda cans explode? When you inhale, your diaphragm increases in volume. How does this allow you to breathe? How does a syringe fill? How does filling a basketball with air increase its volume?

Departmental Problems for Chapter 5: Gases In the 2015 AFC championship football game, it was alleged that the New England Patriots ber the rules by using underinflated footballs. NFL regulations require footballs to be inflated to between 12.5 and 13.5 psi (psi = pounds per square inch). [Note: this is gauge pressure, not ab- solute pressure.] One football actually used in the game was measured to have a pressure of onl 10.5 psi (gauge). One of the Patriots' coaches later alleged that the explanation was due simply gas behavior: pressure decreases as the temperature decreases. Let's examine that last claim. Suppose that the football remained sealed and nearly rigid (i.e. the volume and moles of gas within the ball did not change). A nearby airport measured the air pressure at game time to be 100.95 kPa. The temperature on the field at the start of the game was 51°F. Suppose that the ball was originally inflated in the locker room to the minimum pressure of 12.5 psi (gauge). In order…
Sometimes in lab we collect the gas formed by easy to isolate and measure the amount of gas produced. collected gas chemical reaction over water (see sketch at right). This makes it Suppose the CO, gas evolved by a certain chemical reaction taking place at 40.0 °C is collected over water, using chemical reaction water an apparatus something like that in the sketch, and the final volume of gas in the collection tube is measured to be 71.8 mL. Sketch of a gas-collection apparatus dlo Calculate the mass of CO, that is in the collection tube. Round your answer to 2 significant digits.

Consider 0.1kg of ammonia (NH3) inside a 1.0L container at 0 degree C. determine the quality of NH3. The molar mass of NH3 is 17.03 g/mol
MI < CO C. Under identical conditions, separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simultaneously. After a certain amount of time, it was found that 5.75 mL of O2 had passed through the membrane, but only 3.86 mL of of the unknown gas had passed through.

A flask contains 0.023 M H₂ gas at a pressure of 180 mmHg. Nitrogen gas (N₂) is added to bring the total pressure of the flask to 1.00 atm at constant temperature. a. What is the temperature of the H₂ gas in the flask? b. What is the concentration of N₂ gas in the flask? c. What are the mole fractions of the N₂ and H2 gases in t flask? d. The mixture of N2 and H2 gas reacts to produce ammonia, NH3, according to the equation below. How many moles of NH3 can be formed from the H2 and N2 in the flask? N2 (g) + 3H2(g) → 2NH3(g) e. Which of the gases in the container would have the highest average kinetic energy? f. Which of the gases in the container would have the greatest average speed?
