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
