Chemistry

What is mass?

The amount of matter in a substance.

What is volume?

The amount of space the matter takes up.

What is the definition of the property hardness?

The degree of firmness of a material.

What is the definition of the property color?

Different shades you see from many different atoms. The way a substance looks.

What is the definition of the property luster?

The shininess of a material.

What is the definition of the property viscosity?

The ability of a substance to flow. More viscosity= less flow, less viscosity= more flow.

What is the definition of the property malleability?

The ability for a substance to be flattened into sheets. 2D

What is the definition of the property flammability?

The ability of a substance to burn/ignite.

What is the definition of the property ductility?

The ability of a material to be hammered into a wire.

Whats the definition of the property solubility?

The ability of a substance to dissolve in another substance. Soluble in water= dissolves in water.

What is the definition of the property melting point?

The temperature when a substance changes from a solid to a liquid.

What is the definition of the property boiling point?

The temperature a substance changes from a liquid to a gas.

What is the definition of the property density?

The ratio of mass to volume. Mass/volume.

When there is a heat curve graph, and there is a straight/flat section, what is happening?

A phase change is occurring.

What is the density of water?

1

What is the melting/freezing point of water?

0 degrees Celsius.

What is the boiling/condensing point of water?

100 degrees Celsius.

Are a solids particles more spread out than those of a liquid or gas?

No, solids particles are closer together/more attracted to each other.

Can a gas be compressed?

Yes, because it doesn’t have a definite volume.

What is the definition of a property?

A characteristic or trait used to describe matter, that is true of every sample of a substance.

Is mass and volume a property?

No, because they can be changed due to different factors.
