Matter Flashcards
What is mass
Amount of matter an object has
What is weight
Effect of gravity on the object
What is matter
A bunch of particles that make up something. The something is made of atoms
What do atoms contain
Energy and also are in constant motion
Contain protons, neutrons, electrons.
What happens with more energy
The more movement with particles. The more particles collide
What do faster particles move?
More energy
Solid
Particles have definite shape and occupy definite volume.
Liquid
Takes shape of container, occupies similar volume
Gas
Takes shape of container, volume depends on size of the container
Can everything be a solid liquid or gas
Yes, just needs right conditions
Freezing point
Temperature where liquids turn to solids
Boiling point
Temperature where liquid turns to gas
Condensation
Temperature where gas turns to liquid
Sublimation
Temperature where solid turns to gas
Kinetic molecular theory
All matter is made from small particles All mater contains energy Kinetic energy is energy of motion Helps explain the states of matter More energy the bigger an object Most objects go to a smaller size as it changes forms Water is the exception
Where are protons and neutrons found
Nucleus of an atom
What are the two main parts an atom is made of
Nucleus and electrons
Electrons circle nucleus
What do orbitals have
3D structure and thickness
What are the characteristics of an atom
Protons and neutrons are in nucleus of atom
Atomic mass unit weighs them (AMU)
Electrical charge
Are electrons comparable to protons
No
What is this the electrical charges of protons, electrons,and neutrons
Proton: +1 charge
Electron: -1 charge
Neutron: 0 charge
What does the number of protons do to an element
Defines it. No element has the same amount of protons as another element.
What does an equal number of protons and electrons mean
Neutral I terms of an electric charge
What is an atomic number
Amount of protons/electrons in an element
What is the atomic mass- atomic member
Number of neutrons
Components of atoms
Protons,neutrons, and electrons
What is a protons
symbol, residence, mass,and charge
P
Nucleus
1
+1
What is the neutrons symbol, resident, Mass,charge
N
Nucleus
1
0
Electrons symbol, residents, Mass, charge
E-
Orbitals
0
-1
What do the symbols come from
Word for that element in Latin,Greek, other languages
Isotopes
Element that has a different number of neutrons
What do protons and neutrons do
Give item its mass
How many AMU’s are protons and neutrons
Both 1 AMU
Density
Relationship between mass and volume of an object
Are there spaces between particles, why
Yes, to allow gas to occupy a greater space
What happens when you compress gas
More you compress the hotter it gets
What is put in gas so that you can smell it
Sulphur
What are hydrolics
Force that is applied at one point is transmitted to another point using a incompressible fluid.
Pressure
Continuous physical force exerted on or against an object
Volume
Amount of space something occupies
Viscosity
Fluids ability to flow
What happens when temperature increases
Vescosity decreases
Do thick fluids have high or low viscosity
Thicker the fluid higher the viscosity
What happens to bond strength when temperature increases
Decrease
Volume with temperature increases
Increase
Density when temperature increases
Decrease
Viscosity as temperature increases
Decrease
Pressure as temperature increases
Increase
States of matter
Liquid, solid, gas
