Classification of Matter quiz

Explain the difference between a pure substance and a homogeneous mixture.

• A pure substance contains only one type of particle, while a homogeneous mixture contains multiple types of particles uniformly distributed.

• A pure substance contains multiple types of particles, while a homogeneous mixture contains only one type of particle.

• A pure substance is always a solid, while a homogeneous mixture can be a liquid or gas.

• A pure substance can be separated by physical means, while a homogeneous mixture cannot.

choose the choice that best describes differences between a solid, liquid, and a gas by using the behavior of their particles.

• Solids have particles that are tightly packed and vibrate in place, liquids have particles that are close but can move past each other, and gases have particles that are far apart and move freely.

• Solids have particles that are far apart and move freely, liquids have particles that are tightly packed and vibrate in place, and gases have particles that are close but can move past each other.

• Solids and liquids have particles that are tightly packed, while gases have particles that are close but can move past each other.

• Solids have particles that are far apart and move freely, liquids have particles that are close but can move past each other, and gases have particles that are tightly packed and vibrate in place.
