Ch. 6 - Properties of Matter and Changes in Form

What is matter?

Anything that has mass and takes up space

What are the two categories for all properties of matter?

Physical and chemical

What is density?

Ratio of mass and volume

What is volume?

The amount of space something occupies

Into what two categories are physical properties divided?

Intensive and extensive properties

What is the difference between intensive and extensive properties?

Extensive properties depend on the amount of matter being measured, intensive properties don’t

Which properties can be added together: intensive or extensive?

Extensive

Are size, length, volume, width, mass and weight examples of intensive or extensive properties?

Extensive

Are color, odor, temperature, boiling point, density and state of mater intensive or extensive properties?

Intensive

What are chemical properties?

Characteristics that can only be observed in a chemical reaction

What are some chemical properties?

Reactivity, toxicity, flammability, and combustibility

What is reactivity?

The likelihood of a substance to undergo a chemical reaction

What are the two classifications of changes that matter experiences?

Physical and chemical

Is burning a log into a pile of ashes a physical or chemical change?

Chemical

What is an exothermic reaction?

A physical or chemical reaction that releases heat and energy

What is an endothermic reaction?

A physical or chemical reaction that absorbs heat and energy

Is making ice cubes an exothermic or endothermic reaction?

Exothermic
