Gases expand to occupy whatever volume is available. O d. Gases easily diffuse into one another. O e. Gases are described in terms of their temperature, pressure, volume, and number of moles of gas present.

Which concept best accounts for the fact that gases can escape through a pinhole faster at higher temperatures? Select one: O a. A gas is composed of molecules whose size is much smaller than the distances between them. O b. Gas molecules move randomly--at various speeds and in every possible direction. O c. Except when molecules collide, forces of attraction and repulsion between them are negligible. d. When collision occur, they are elastic. Oe.

5. If the temperature of a gas at 3.4 atm decreases from 100°C to -100°C, what will the pressure become?

What happens to the pressure of a gas if it is cooled down while the volume of the container it is in remains constant? Select one: O a. pressure decreases O b. pressure remains the same O c. pressure increases O d. it cannot be predicted A 5.6 liters sample of gas in a piston has a pressure of 1.5 atm. The piston is compressed until its volume is 4.8 L. What is the new pressure of the gas inside the piston (in atm)? DO NOT INCLUDE UNITS IN YOUR FINAL ANSWER. Answer: A small research submarine with a volume of 1.2 x 105 L has an internal pressure of 1.0 atm and an internal temperature of 15 °C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 3° C, what will the volume of the gas (in L) inside be if the hull of the submarine breaks? Put your answer in 3 sig figs, DO NOT INCLUDE UNITS IN YOUR FINAL ANSWER. Answer: Which of the following is NOT a property of cases?
