Unit 1 Mod 1 Lesson 1 Quiz Topics-States of Matter and Chemical Formulas (Middle School Science)

Flashcards created from the Unit 1 Mod 1 Lesson 1 Quiz Topics checklist, covering matter, energy definitions, particle movement, temperature effects, and atomic counts.

What happens to thermal energy when energy is added?

Thermal energy increases as energy is added.

How does particle movement differ in cold versus warm temperatures?

Particles move slower at cold temperatures and faster at warm temperatures.

How is kinetic energy different across the states of matter (solid, liquid, and gas)?

Solids have the lowest kinetic energy, liquids have moderate kinetic energy, and gases have the highest kinetic energy.

How do particles move in a solid, a liquid, and a gas?

In a solid, particles vibrate in fixed positions; in a liquid, particles slide past each other; and in a gas, particles move freely and rapidly.

How are particles in gases arranged?

Particles move freely and rapidly. They have no definite shape or volume and take the shape of the container they are in.

How are particles in solids arranged?

The particles vibrate minimally in place. They have a definite shape and volume.

How are the particles in liquid arranged?

The particle in a solid bounce and flow off each other, and have no definite shape, but have a definite volume.

Which state of matter is this the particles arrangement of in the diagram?

Solid
