What is the relationship between gas molecules and their kinetic energy?

• Gas molecules are at large distances from each other and have low kinetic energy.

• Gas molecules are at small distances from each other and have low kinetic energy.

• Gas molecules are at large distances from each other and have high kinetic energy.

• Gas molecules are at small distances from each other and have high kinetic energy.

Units of Pressure can be expressed in standard atmosphere, pascal, torr and (a)  

Which of the following gas laws states that the volume of a gas is directly proportional to its temperature (in Kelvin) at constant pressure?

• Boyle's law

• Charles's law

• Avogadro's law

• Dalton's law

According to Avogadro's law, at constant temperature and pressure, equal volumes of gases contain equal numbers of (a)   .

Which of the following statements best describes the behavior of an ideal gas?

• It has no intermolecular forces.

• It obeys all gas laws exactly.

• It behaves similarly to real gases at all conditions.

• It has a non-zero volume.

According to Dalton's law of partial pressures, the total pressure exerted by a mixture of gases is equal to:

(a)  

Liquids adapt to the space they occupy due to their (a)  

Which are the fundamental principles in the study of gases?

What is the main reason why solids have a definite shape and volume?

• Due to a fixed arrangement of particles

• Due to a random arrangement of particles

• Due to a lack of particles

• Due to a liquid state

The ideal gas law is expressed as:

• P = (nRT)/V

• P = nRT/V

• PV = nRT

• P = nR/T
