1. What is the primary assumption of the kinetic theory of gases?

Gases are made of large particles · Gas particles are in constant random motion · Gas particles attract each other · Gases occupy no volume

2. According to the kinetic theory, the pressure exerted by a gas is due to:

The weight of the gas molecules · The collisions of gas molecules with the walls of the container · The temperature of the gas · The volume of the gas

3. In an ideal gas, the average kinetic energy of a molecule is directly proportional to:

The pressure of the gas · The volume of the gas · The absolute temperature of the gas · The number of molecules

4. What does the root mean square speed of gas molecules depend on?

Mass and temperature of the gas · Pressure and volume of the gas · Density and temperature of the gas · Number of molecules in the gas

5. Which of the following statements is true for an ideal gas?

Molecules have significant volume · Molecules experience intermolecular forces · Collisions between molecules are perfectly elastic · Molecules do not move randomly
