Kinetic Molecular Theory & Pressure of Gas

Kinetic molecular theory of gas is proposed by:

• Albert Einstein
• Marie Curie
• Isaac Newton
• Daniel Bernoulli

Which of them is kinetic equation of gas proposed by Clausius:

• PV = nRT

• PV = ⅓ mNc²

• KE α T

• P = F/A

The pressure of a gas is define as:

• The volume of the gas per unit area.
• The temperature of the gas per unit area.
• The density of the gas per unit area.
• The force exerted by the gas per unit area.

What is mean free path of a gas?

• The mean free path of a gas is the average distance traveled by a molecule before it collides with the container walls.
• The mean free path of a gas is the average distance traveled by a molecule before it reacts with another molecule.
• The mean free path of a gas is the average distance traveled by a molecule between collisions with other molecules.
• The mean free path of a gas is the average distance traveled by a molecule before it undergoes a phase change.

According to the kinetic molecular theory of gas, the collision between the molecules of gas is:

• explosive
• elastic
• inelastic
• static

According to the kinetic molecular theory of gas, the attraction between the molecules of an ideal gas is:

• negligible or zero
• intermediate
• weak
• strong

According to the kinetic molecular theory of gas, the mass of individual molecule of gas as compared with total gaseous sample is:

• smaller

• equal
• larger
• negligible

14.7 Psi equals to:

• 101325 N/m²

• 14.7 atm

• 1 torr

• 760 torr

1000 torr is equal to:

• 1.5 atm
• 0.987 atm
• 2.6316 atm
• 1.3158 atm

The pressure of a gas is measured with the help of apparatus having J shaped tube filled with mercury called:

• manometer
• hydrometer
• thermometer
• barometer
