Chemistry chapter 5

What is the basic assumptions in Kinetic Molecular Theory?

• Intermolecular forces of attraction does not exist between gas particles

• Intermolecular forces of attraction exist between gas particles

• The collisions between gaseous particles are perfectly effective

• A gas consist of tiny particles of negligible volume

The average kinetic energy of a gas molecules is __________________

to the absolute temperature.

What is the definition of Avogadro's Law?

• Volume of gas directly proportional to the number of moles of the gas present

• Volume of gas inversely proportional to the number of moles of the gas present

Combined Gas Law:

• Avogadro's Law

• Boyle's Law

• Charles's Law

• Dalton's Law

Ideal Gas Law:

• Avogadro's Law

• Charles's Law

• Daltons' Law

• Boyle's Law

What is partial pressure?

• The pressure that a gas would exert if it were present alone in the container

• The pressure that a gas would exert if there are other molecules present in container

What is the condition so the Dalton's Law can be applied?

• Mixture contains only one gas

• Mixture contains two or more gases

Condition where Ideal Gas occur:

• High pressure

• Low pressure

• Low temperature

• High temperature

Properties of liquid can be explained at some aspects such as:

• Temperature

• Shape and volume

• Viscosity

• Surface tension

• Compressibility and Diffusion

What is the difference between vaporisation process and boiling process?

• VP: occurs at any temperature

• BP:occurs at specific temperature and pressure

• BP: occurs at any temperature

• VP:occurs at specific temperature and pressure
