Classification of Matter
Anything that has mass and takes up space (has volume) is defined as
matter
Characteristics of matter that can be observed or measured without changing the substance's identity are
physical properties
properties of a solid are?
definite shape and definite volume
what happens to the temperature of a substance when it undergoes a state change
it stays constant
what principle states that a change in pressure at any point in an enclosed fluid is transmitted equally to all parts of the fluid.
Pascal's Priciple
The smallest unit of an element that maintains the chemical properties of that element is a(n)
atoms
Characteristics that describe a substance's ability to participate in chemical reactions and form new substances are
chemical properties
what state of matter has a definite volume, but changes shape and takes the shape of its container
liquid
As temperature of a substance increases whats happens to the particles?
they move faster
when the car tire pressure drops this is an example of what law?
as temperature decreases so does pressure
Gay-Lussac’s Law

Immiscible
what is the density equation?
D=M/V
when a solid goes to a gas
sublimation
According to Kinetic Theory, all matter is made of tiny particles that are in constant
motion
What law describes as an inflated balloon will pop when it gets too hot.
temperature increases volume increaes
Charles Law

You have a rock with a mass of 12.0g and a volume of 3 cm^3. What is its density?
12/3=4g/cm^3
what is the difference between a gas and plasma
plasma is electrically charged
why does your body feel cooler when you sweat?
heat loss leaves cooler, lower energy particles behind
Why shouldn't pressurized containers such as spray cans be heated
Because of Gay-Lussacs law the can will explode
T increases
P increases
