Unit 4 States of Matter Review

Front

Where are the metalloids found on the periodic table?

Back

Metalloids are found along the stair-step line (diagonal) on the periodic table.

Front

Which of the following is NOT a characteristic of most metals?

Back

Brittle.

Front

What state of matter is characterized by particles that are tightly held together with very tiny movement, having a definite shape and fixed volume?

Back

Solid.

Front

True or False: The atoms in a solid move slower than atoms in a liquid.

Back

True.

Front

What state of matter do atoms form when they are widely spaced and move freely?

Back

Gas.

Front

Define 'solid' in terms of particle arrangement and movement.

Back

A solid has particles that are closely packed together, with limited movement, resulting in a definite shape and volume.

Front

What is the primary characteristic that distinguishes liquids from solids?

Back

Liquids have a definite volume but take the shape of their container, while solids have a definite shape.

Front

What happens to the movement of particles when a substance changes from a solid to a liquid?

Back

The particles gain energy and move more freely.

Front

What are the three main states of matter?

Back

Solid, liquid, and gas.

Front

How do gases differ from solids and liquids in terms of particle arrangement?

Back

Gases have particles that are far apart and move freely, unlike solids and liquids where particles are closer together.
