- How does heating and cooling cause changes in matter?
- Heating and cooling will cause matter to change state.
- How are the mass and volume of an object different?
- Mass is the amount of material that an object has in it. Volume is the amount of space that matter takes up.
- How does baking pancakes produce a different kind of matter?
- The liquid in the batter is released as a gas. The liquid batter changes into a solid.
- balance
- an instrument used to measure an object's mass
- What metric units are used to measure mass?
- Grams and kilograms are used to measure mass.
- freezing point
- the temperature at which matter changes from a liquid to a solid
- Name four physical changes that can happen to material.
- Changes in size shape, color, and stae of matterare all physical changes.
- physical change
- a change in matter that change physical properties, but does not produce a different kind of matter
- How is a solution different from other mixtures?
- In a mixture the substances to not blend evenly. In a solution the substances blend evenly throughtout the another substance (salt and water solution--usually one substance will disolve in the other)
- volume
- the amount of space that matter takes up
- What are two different units scientists use to measure volume?
- Scientists use cubic meters,liters and graduated cylinders to measure volume.
- density
- how much mass is in a certain volume of matter
- Name three examples of chemical changes other than cooking.
- Burning, tarnishing and rusting are other examples of a chemical change.
- boiling point
- the temperature at which matter changes from a liquid to a gas
- How is density different than mass?
- Mass is the amount of material in an object. Density is the amount of mass in a certain volume of matter. (water and syrup)
- graduated cylinder
- a tool used to measure the volume of liquids
- chemical change
- a change in matter that produces a different kind of matter
- melting point
- the temperature at which matter changes from a solid to a liquid
- mixture
- two or more substances that are mixed together but can be easily separted
- What are two physical properties of matter?
- A property is something about matter that can be observed and tells you what the matter is like. color, shape, size, mass, state(liquid, gas, solid) ability to float.
- meter
- a unit for measuring length
- kilogram
- a metric unit of mass equal to 1,000 grams
- mass
- the amount of material that an object has in it
- cubic meter
- a unit for measuring the volume of a solid
- liter
- a unit for measuring volume
- gram
- the basic unit for measuring mass
- solution
- a mixture in which one substance spreads evenly throughout another substance
- matter
- anything that has mass and takes up space
