U5: Physical Properties of Materials Review

Front

What are the physical properties of metals?

Back

Metals are typically shiny, malleable, ductile, good conductors of heat and electricity, and have high melting and boiling points.

Front

What are the physical properties of nonmetals?

Back

Nonmetals are usually dull, brittle, poor conductors of heat and electricity, and have lower melting and boiling points compared to metals.

Front

What is the state of matter with the greatest distance between particles?

Back

Liquid has a greater distance between particles compared to solids.

Front

How are particles arranged in a solid?

Back

In a solid, particles are closely packed together in a fixed arrangement.

Front

What type of compounds are all solids at room temperature?

Back

Ionic compounds are typically solids at room temperature.

Front

What is the triple point in a phase diagram?

Back

The triple point is the condition at which all three phases (solid, liquid, gas) coexist in equilibrium.

Front

What is the difference between solids and liquids in terms of particle arrangement?

Back

In solids, particles are tightly packed and fixed in place, while in liquids, particles are close but can move past each other.

Front

What is a characteristic of gases regarding particle distance?

Back

Gases have particles that are far apart and move freely, resulting in low density.

Front

Define malleability in terms of physical properties of materials.

Back

Malleability is the ability of a material to be deformed under compressive stress, allowing it to be shaped into thin sheets.

Front

What is ductility?

Back

Ductility is the ability of a material to be stretched into a wire without breaking.
