1.5.2 States of Matter

• What is matter defined as?

  Mass and occupies space
• How many states of matter are there?

  Four
• Liquids are highly compressible.

  False
• The fourth state of matter is called plasma
• Solids have a definite shape and volume due to the strong intermolecular forces
• Why do liquids have a definite volume but no definite shape?

  Moderate intermolecular forces
• Where is plasma commonly found in nature?

  Stars and lightning
• Ice is an example of a solid.

  True
• Gases have no fixed shape or volume due to weak intermolecular forces.


  True
• Match the property with the state of matter:

  Definite Shape ↔️ Solid

  Definite Volume ↔️ Liquid

  High Compressibility ↔️ Gas

  Ions and Free Electrons ↔️ Plasma
• Liquids have a definite shape but no definite volume.

  False
• Name three examples of gases.

  Air, helium, carbon dioxide
• What are the two key characteristics of gases regarding their shape and volume?

  No definite shape or volume
• What is the fourth state of matter?

  Plasma
• Plasma has high electrical conductivity due to the presence of ions and free electrons
• Why do liquids have a definite volume but no definite shape?

  Disordered particle arrangement
• Match the state of matter with its definite properties:

  Solid ↔️ Definite shape and volume

  Liquid ↔️ Definite volume, no definite shape

  Gas ↔️ No definite shape or volume

  Plasma ↔️ Ionized particles
• What is an example of a liquid that demonstrates the properties of liquids?

  Water
• Solids have a definite shape and volume.


  True
• Match the state of matter with its intermolecular forces:

  Solid ↔️ Strong

  Liquid ↔️ Moderate

  Gas ↔️ Weak
• What shape does a liquid take?

  Container
• Which state of matter has the highest electrical conductivity?

  Plasma
• What is the fourth state of matter in addition to solid, liquid, and gas?

  Plasma
• Gases are highly compressible because their particles are highly disordered with weak intermolecular forces.


  True
• What property defines liquids besides a definite volume?

  No definite shape
• Match the state of matter with its intermolecular forces:

  Solid ↔️ Strong

  Liquid ↔️ Moderate

  Gas ↔️ Weak
• Solids have low compressibility because strong intermolecular forces keep particles in an ordered
• Matter is anything that has mass and occupies space.
• What type of intermolecular forces do gases have?

  Weak
• Arrange the states of matter from strongest to weakest intermolecular forces:

  1️⃣ Solid

  2️⃣ Liquid

  3️⃣ Gas
• Liquids exhibit low compressibility because their particles are relatively close together.
• What type of particle arrangement do gases have?

  Highly disordered
• Plasma has high electrical conductivity due to the presence of ions and free electrons.


  True
• Gases are highly compressible due to their weak intermolecular forces
• Plasma is found in high-temperature environments like stars and lightning.


  True
• Order the states of matter based on increasing intermolecular forces:

  1️⃣ Gas

  2️⃣ Plasma

  3️⃣ Liquid

  4️⃣ Solid
• Gases are highly compressible because their particles are close together.

  False
• Liquids have a definite volume but no definite shape
• Match the state of matter with its particle arrangement:

  Solid ↔️ Ordered

  Liquid ↔️ Disordered

  Gas ↔️ Highly Disordered
• What is the fourth state of matter in addition to solid, liquid, and gas?

  Plasma
