Anything that has mass and takes up space
What is matter?
The color of an item is an example of this.
What is a physical property?
This substance is made up of ONE type of atom
What is an element?
Anything that flows (gas or liquid)
What is a fluid?
A caesar salad is an example of this
What is a heterogenous mixture?
Has a definite shape and volume
What is a solid?
Cutting up paper is an example of this.
What is a physical change?
Matter can be classified into two sub-categories
What are substances and mixtures?
The ability for a fluid to exert an upward force on an object
What is buoyancy/the buoyant force?
The reason dye sinks faster in cold liquid
The particles move slower/Kinetic molecular theory
Has an indefinite shape and a definite volume
What is a liquid?
Hydrogen peroxide denaturing (breaking down) when being exposed to light is an example of this.
What is a chemical property/change?
This material is made up of 2 or more substances and CAN be separated by physical means
What is a mixture?
Any pressure exerted on a fluid is transmitted the same amount through the whole fluid
What is Pascal's principle?
The Tyndall effect happens in these two mixtures
What are colloids and suspensions?
The size of a substance increases when heated and contracts when cooled. The exception to this is water.
What is thermal expansion?
"Matter cannot be created or destroyed"
What is the 1st Law of Thermodynamics/The Law of Conservation of Mass?
This material has dissolved particles that you cannot see with the naked eye
What is a solution?
This principle allows airplane wings to create lift
What is Bernoulli's principle?
Water/H2O and limestone/CaCO3 are both examples of this.
What is a compound?
The state change when a solid transforms directly into a gas.
What is sublimation?
List at least three signs of a chemical change
Change in color, change in odor, formation of a gas, temperature change, formation of a precipitate, emission of light
This specific type of mixture may produce the Tyndall effect but also needs shaking to mix
What is a heterogenous suspension?
As the volume of gas decreases the pressure increases
What is Boyle's Law?
PbI and KCl and H are put in a bowl. This is?
What is a mixture of elements and compounds?
