Applications of Gas Laws

Which of the following would increase the pressure of a gas? Choose all that apply. An increase in the number of molecules of gas. A decrease in the number of molecules of gas. A decrease in temperature. An increase in temperature. An increase in volume of the container. A decrease in volume of container. A beach ball inflated during a sunny day is left out overnight. In the morning, the ball appears to be deflated. Assuming there are no leaks in the ball, this illustrates a relationship between which two variables? Temperature Amount of gas in ball Pressure Volume If the pressure from a gas increases while the volume remains constant, the temperature of the gas will _. increase. decrease. stay the same. When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the air molecules hit the walls of the tire less frequently . air molecules diffuse rapidly through the walls of the tire. rubber in the tires reacts with oxygen in the atmosphere . air molecules speed up and collide with the tire walls more often . Which container would have a higher pressure? Left Right They are the same. 55 gallon drum crush Explain what is happening in terms of temperature and pressure using complete sentences and academic vocabulary. Be sure to include the pressure inside and outside of the drum. Watch the video having to do with peeps being placed in a vacuum. There are gasses trapped inside of marshmallows (and peeps). Describe what is happening in the vacuum chamber in terms of pressure and volume. Be sure to use complete sentences and use academic vocabulary. Which gas law is demonstrated with the peeps in the vacuum chamber? Charles' Law Boyle's Law Gay-Lussac's Law Combined gas law Many people throw away ping pong balls that are dented. Explain how, using Charles' law, these ping pong balls could be restored to their original shape. According to Charles Law, if you have a balloon inside a car at noon during a hot summer day, the balloon molecules inside will increase in pressure. True or false? True False A sample of nitrogen gas has occupied a volume of 500ml at a pressure of 0.971atm. What volume will the gas fill at a pressure of 1.50 atm, assuming the temperature remains constant? 342 mL 424 mL 324 mL 442 mL 242 mL Gas pressure is caused by gas molecules heating up. gas molecules colliding with one another. gas molecules colliding with the walls of a container. gas molecules reacting with other gas molecules. If each flask contains the same number of molecules of gas, which has the highest pressure? 1 2 3 4 Is the following statement true or false. Justify.A good application of Charles' law is that a piece of metal expands when heated.
