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.
