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

Heat - measure of the quantity or how much energy Temperature - measure of the intensity or how energetic each particle is

Temperature Conversion K = °C °C = 5/9 (°F – 32) °F = 9/5 * °C + 32
