Kinetic Molecular Theory

A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as

• real gas

• ideal gas

• imaginary gas

• perfect gas

Which of the following is not true about the volume of a gas?

• Most of the volume is empty space.

• The volume is occupied by particles in continuous, rapid, random motion.

• The volume is about 10 times greater than that occupied by an equal number of particles in the liquid or solid state.

• Generally, the volume can be easily changed

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

Which of the following is the equation needed to calculate the kinetic energy, KE, of a moving particle?

• KE = 1/2 mv²

• KE = 2mv

• KE = mv

• KE = 1/2 m²v

Which condition is necessary for most gases to behave nearly ideally?

• high pressure

• high temperature

• low compressibility

• low expansion

For a fixed amount of gas at a constant temperature, the volume increases as the pressure...

• remains steady.

• increases.

• decreases.

• fluctuates.

The pressure exerted by a gas does not depend on

• temperature.

• volume.

• number of moles present.

• the identity of the gas.

Which temperature scale cannot have negative numbers

• Fahrenheit

• Celsius

• Kelvin

• Degrees

Forces of attraction or repulsion between molecules are called:

• Electronegativity

• Covalent Bonds

• Ionic Bonds

• Intermolecular Forces
