3.2.1 States of Matter

• What are the three states of matter?

  Solids, liquids, and gases
• Solids have a fixed shape and volume because their particles are tightly packed in a regular pattern.
• Liquids maintain a fixed volume but take the shape of their container.
• What are the shape and volume properties of gases?

  No fixed shape or volume
• Match the state of matter with its particle arrangement:

  Solid ↔️ Tightly packed, regular pattern

  Liquid ↔️ Close, can move past each other

  Gas ↔️ Widely spaced, move randomly
• Why do solids have a fixed shape and volume?

  Particles are tightly packed
• The particles in liquids are close together but can move past each other.
• Arrange the states of matter based on increasing particle freedom:

  1️⃣ Solid

  2️⃣ Liquid

  3️⃣ Gas
• Gases expand to fill any container because their particles are widely spaced.
• What determines the shape and volume of each state of matter?

  Arrangement and movement of particles
• Why do solids have a fixed volume?

  Particles are tightly packed
• Liquids have a fixed volume but can change their shape based on the container.
• Gases have neither a fixed shape nor volume.
• Match the property of each state of matter with its characteristic:

  Solid ↔️ Fixed shape and volume

  Liquid ↔️ Fixed volume, variable shape

  Gas ↔️ No fixed shape or volume
• Arrange the states of matter based on increasing particle movement:

  1️⃣ Solid

  2️⃣ Liquid

  3️⃣ Gas
• What are the three states of matter and what determines their properties?

  Solids, liquids, and gases; particle arrangement
• What determines the properties of the three states of matter?

  Particle arrangement and movement
• What is the shape of a liquid?

  Takes shape of container
• Gases fill both their shape and volume
• Match the state of matter with its correct property:

  Solid ↔️ Fixed shape and volume

  Liquid ↔️ Fixed volume, variable shape

  Gas ↔️ Variable shape and volume
• What results in the distinct characteristics of each state of matter?

  Particle arrangement
• The arrangement and movement of particles in each state of matter are distinct
• Match the state of matter with its particle movement:

  Solid ↔️ Vibrate in fixed positions

  Liquid ↔️ Move past each other

  Gas ↔️ Move freely
• In solids, particles vibrate in fixed positions.
• In liquids, particles are close but can move past each other
• How do gas particles move?

  Widely spaced, move freely
• Order the states of matter from least to most particle movement:

  1️⃣ Solid

  2️⃣ Liquid

  3️⃣ Gas
• What are the three states of matter?

  Solids, liquids, gases
• Solids have a tightly packed, regular particle arrangement.
• Liquids take the shape of their container
• What is the particle arrangement in gases?

  Widely spaced, move randomly
• Order the states of matter from highest to lowest particle density:

  1️⃣ Solid

  2️⃣ Liquid

  3️⃣ Gas
• What are the three states of matter?

  Solids, liquids, gases
• The properties of the states of matter are determined by the arrangement and movement of their particles
• Solids have a fixed shape and fixed volume.
• What shape does a liquid take?

  Shape of container
• Gases fill the container they are in.
• The differences in particle arrangement lead to distinct characteristics for each state of matter.
• Describe the particle arrangement in a solid.

  Tightly packed, regular pattern
• In a liquid, particles are close but can move past each other, resulting in a fixed volume
