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.
