    Study Notes

    Matter

    • Anything that has mass and takes up space.
    • Exists in three states: solid, liquid, and gas.

    States of Matter

    • Solid: Has a definite shape and volume.
    • Liquid: Has a definite volume but takes the shape of its container.
    • Gas: Has no definite shape or volume and fills its container.

    Changes in Matter

    • Melting: The process of a solid changing into a liquid.
    • Freezing: The process of a liquid changing into a solid.
    • Evaporation: The process of a liquid changing into a gas.
    • Condensation: The process of a gas changing into a liquid.

    Matter

    • Matter is anything that has mass and takes up space.

    Mass

    • Mass is measured in grams.
    • A triple beam balance is used to measure mass.

    Volume

    • Volume is the amount of space an object occupies.
    • Volume is measured in cubic centimeters (cm³).
    • Regularly shaped objects have volume calculated by multiplying length, width, and height.
    • Irregularly shaped objects have volume measured by water displacement using a graduated cylinder.

    States of Matter

    • Solid: Definite shape and volume.
    • Liquid: Definite volume, takes the shape of its container.
    • Gas: No definite shape or volume, fills its container.

    Changes in Matter

    • Melting: Solid to liquid.
    • Freezing: Liquid to solid.
    • Evaporation: Liquid to gas.
    • Condensation: Gas to liquid.

    Matter

    • Matter is anything that has mass and takes up space.
    • Mass is the amount of matter in an object.
    • Mass is measured in grams using a triple beam balance.
    • Volume is the amount of space an object takes up.
    • Volume can be measured in different ways depending on the shape of the object.

    Measuring Volume

    • The volume of a regularly shaped object can be measured by multiplying length, width, and height (length x width x height).
    • The volume of an irregularly shaped object can be measured by water displacement using a graduated cylinder.

    States of Matter

    • Solids have a definite shape and volume.
    • Liquids have a definite volume but take the shape of their container.
    • Gases have no definite shape or volume and fill their container.

    Changes in Matter

    • Melting is the change of state from a solid to a liquid.
    • Freezing is the change of state from a liquid to a solid.
    • Evaporation is the change of state from a liquid to a gas.
    • Condensation is the change of state from a gas to a liquid.

    Density

    • Density is a measure of how much mass is packed into a given space.
    • To calculate density, divide the mass of the object by its volume (Density = Mass / Volume).
    • Objects with a density less than 1 g/cm3 will float in water.
    • Objects with a density greater than 1 g/cm3 will sink in water.

    Qualitative and Quantitative Data

    • Qualitative data are observations made using your senses.
    • Quantitative data are observations that are measurable using scientific instruments.
