Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements is NOT a postulate of the Kinetic Molecular Theory of gases?
Gas particles are in continuous, random motion.
The volume of individual gas particles is negligible compared to the volume of the container.
Attractive and repulsive forces exist between gas particles.
Collisions between gas particles and container walls are elastic.
2. An ideal gas is confined in a container at a constant temperature. If the pressure of the gas is doubled, what happens to its volume?
It doubles.
It halves.
It remains the same.
It quadruples.
3. According to Boyle's Law, at constant temperature, the pressure and volume of a gas are proportional.
4. Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its absolute .
5. Explain the difference between an ideal gas and a real gas. Under what conditions do real gases behave most like ideal gases?
6. Increasing the temperature of a gas while keeping its volume constant will decrease its pressure.
True
False
7. A gas occupies a volume of 2.50 L at 1.00 atm pressure. If the pressure is increased to 3.00 atm while the temperature remains constant, what is the new volume of the gas?
