States of Matter
anything that has mass and takes up space
What is matter?
Solid, Liquid, gas
What are the 3 basic states of matter?
This results in a new substance and is permanently changed
What is a Chemical change?
This physical property tells you how tightly packed the particles are in a substance
What is density?
A property that can be observed/measured without changing its identity is called....
What are physical properties
This substance has a definite shape and define volume.
What is a soild?
When enough heat is added to a solid, it melts and becomes this state of matter
What is a liquid?
A change in matter that involves a change in a physical property but doesn't create a new substance
What is Physical change?
If a substance has a density of 8 g/cm³, and the density of water is 1 g/cm³, this substance will do this when placed in water
What is sink?
The point at which a solid turns to liquid is called this
What is the melting point?
This has no definite shape, but does have a definite mass and volume
What is a Liquid?
If a liquid undergoes enough cooling, it will become this state
What is a solid?
Which change occurs when milk goes sour?
What is a chemical change?
This is the formula for calculating the density of a substance
What is mass divided by volume
g/cm3 or g/ml
What are the units for density?
Atoms packed closely together in this state and they vibrate in place
What is a solid?
The phase change of a liquid going to gas is called...
What is evaporation
Melting wax, thick honey, and shiny metal are all what type of properties?
What are physical properties?
Length and volume are an example of this
What is extensive properties
This is the property of a material that allows it to carry electricity
What is electrical conductivity?
If enough heat is added to a liquid it become this state.
What is a gas?
This phase change occurs when a solid turns directly into a gas, skipping the liquid phase
What is sublimation?
Rust, tarnished silver and corrosion are all examples of this
What are chemical changes?
If the density of an object is less than that of the liquid it is placed in, the object will do this
What is float?
Toxicity is an example of this...
