Matter Chatter
Anything that has volume and mass
Matter
Our opening lab with the bag of M&M's had you listing off what? These things could be observed or measured without changing the identity of the matter.
Physical Properties
Chemical properties describe a substance based on its ability to change into a NEW substance with ___________.
different properties
What is mass?
The amount of matter something is made of.
The amount of space taken up/occupied by an object.
Volume
A physical change is a change that affects one or more physical properties of a substance. This (will/will not) form a new substance?
Will NOT
The properties that are most useful in identifying a substance that are always the same are?
Characteristic Properties
An objects mass can ONLY be changed if we change the amount of_________.
Matter
When measuring the volume of a liquid, we look at the bottom of this.
Meniscus
Density is the amount of matter in a given space. What is the equation for Density?
D=m/V
What is is called when one or more substances are changed into entirely new substances wither different properties?
Chemical Change
_________ is the force of attraction between objects that is due to their masses.
Gravity
Solid volume is LxWxH, this means that the answer is?
m3: Cubed
Density can be used to identify a substance because?
It does not change with the size of the object.
Chemical changes (can/cannot) be undone.
Cannot
Though commonly confused, mass and weight are not the same because weight measures?
the amount of gravitational force on an object.
Gas expands to fill its container, so we can measure it's volume if we know?
The volume of the container.
What happens when liquids with different densities are put in the same container?
They will separate into layers.
Baking a cake is an example of a chemical change, what are some of the clues that these changes have happened?
(1)a new substance is formed (2)color change (3)production of odor(4)gas bubbles formed in cake
_________ is the tendency of an object to resist a change in motion.
Inertia
