Four words that mess with your head

Atom – single building block from the periodic table

Element – more than one building block from the periodic table

Compound – two or more atoms joined together (ionic)

Chemistry

The Study of Matter and the Changes it undergoes

The Study of Matter

• Matter - Occupies Space and has mass

The Study of Matter

• Matter - Occupies Space and has mass

• Mass - Measure of the quantity of Matter

The Study of Matter

• Matter - Occupies Space and has mass

• Mass - Measure of the quantity of Matter

• Weight - Measure of the force of attraction

MATTER

Pure substance - Has fixed composition and distinct properties

MATTER

Pure substance - Has fixed composition and distinct properties– Element - Substance that cannot be broken into a

simpler substance without loosing its properties

MATTER

• Pure substance - Has fixed composition and distinct properties– Element - Substance that cannot be broken into a

simpler substance without loosing its properties– Compound - Composed of two or more elements

MATTER

Mixture - Composed of two or more substances which retain their individual identities– Homogeneous mixture - Mixture that is uniform

throughout– Heterogeneous mixture - Mixture that is not

uniform throughout

Ohhh My What is the Matter……..

……It’s all a matter of chemistry

• Heat - measure of the quantity or how much energy

• Temperature - measure of the intensity or how energetic each particle is

Temperature Conversion

K = °C + 273

°C = 5/9 (°F – 32)

°F = 9/5 * °C + 32
