The Study of Matter • Matter - Occupies Space and has mass • Mass - Measure of the quantity of Matter • Weight - Measure of the force of attraction • Physical properties - Characteristics of the substance. (Color, Hardness, Density, Etc.) • Chemical Properties - How one substance reacts with another.
ENERGY The capacity for doing work Or The ability to change matter
ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position
ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position • Kinetic energy - Energy due to motion
ENERGY The capacity for doing work The ability to change matter • Potential energy - Energy due to position • Kinetic energy - Energy due to motion • Chemical energy - The energy released as a reaction occurs
The States of Matter • Solid - Maintains shape and volume
The States of Matter • Solid - Maintains shape and volume • Liquid - Maintains volume, takes the shape of the container
The States of Matter • Solid - Maintains shape and volume • Liquid - Maintains volume, takes the shape of the container • Gas - No definite volume, takes the shape of its container
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 • 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 • Mixture - Composed of two or more substances which retain their individual identities
MATTER • Mixture - Composed of two or more substances which retain their individual identities • Homogeneous mixture - Mixture that is uniform throughout
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
The Chemical Element • The letters on the periodic table are like the alphabet to chemists
The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties
The Chemical Element • The letters on the periodic table are like the alphabet to chemists • Each Element has distinct properties • When elements combine, they are written with subscripts indicating how many of each element there is.
