Exploring States of Matter

What are the three main states of matter?

• mist

• plasma

• solid, liquid, gas

• vapor

What is a phase change?

• A phase change is the transition of a substance between different states of matter.

• A phase change is the change in temperature of a substance.

• A phase change refers to a chemical reaction.

• A phase change is the process of mixing two substances.

What happens to the particles in a solid?

• Particles in a solid move freely and are widely spaced apart.

• Particles in a solid are in constant motion and can change shape easily.

• Particles in a solid are completely still and have no interaction with each other.

• Particles in a solid vibrate in fixed positions and are closely packed together.

How do liquids take the shape of their container?

• Liquids take the shape of their container due to the ability of their molecules to move and rearrange freely.

• Liquids take the shape of their container because they are solid at room temperature.

• Liquids maintain a fixed shape regardless of their container.

• Liquids take the shape of their container due to the presence of strong intermolecular bonds.

What is the property of gases that allows them to expand?

• Gases are heavier than liquids and cannot expand.

• Gases are composed of tightly packed particles that do not move.

• The property of gases that allows them to expand is their ability to have particles that are widely spaced and in constant motion.

• Gases have fixed volumes and cannot change shape.

What is melting in terms of phase change?

• Melting is the phase change from solid to liquid.

• Melting is the phase change from gas to solid.

• Melting is the phase change from solid to plasma.

• Melting is the phase change from liquid to gas.

What is the difference between a solid and a liquid?

• Liquids have a fixed shape and volume, while solids do not.

• Solids can flow while liquids cannot.

• Solids are always heavier than liquids.

• The main difference is that solids have a fixed shape and volume, while liquids have a fixed volume but take the shape of their container.

How does temperature affect the state of matter?

• Temperature only affects the color of matter.

• Temperature changes do not influence the state of matter.

• Temperature changes can cause matter to transition between solid, liquid, and gas states.

• Matter remains unchanged regardless of temperature.

What is evaporation?

• Evaporation is the process of vapor condensing into a solid.

• Evaporation is the process of gas turning into liquid.

• Evaporation is the process of solid turning into liquid.

• Evaporation is the process of liquid turning into vapor.

What are some common properties of gases?

• Inability to diffuse and effuse

• Common properties of gases include low density, high compressibility, no fixed shape or volume, and the ability to diffuse and effuse.

• High density

• Fixed shape and volume
