solid, liquids, gases, plasma
What are the basic states of matter plus a fourth less known state?
crystalline solids and made entirely of carbon atoms that form crystals. amorphous solids are found in random arrangement. ( rubber, plastic, and glass)
What is the difference between crystalline solids and amorphous solids?
Give two examples of crystalline solids and two examples of amorphous solids.
a liquid's resistance to flow.
Define the term viscosity.
the uneven forces acting on the particles on the surface of a liquid.
How does surface tension relate to liquids?
it is a vapor when a liquid or solid at room temperature. example: water is a liquid a room temp
When is gas considered a vapor?
the motion of the particles and the strength of atrraction between the particles a material's state of matter
What determines a material's state of matter?
What motion do solid particles have?
the particles at the surface experience different forces than those at the center of the liquid
Why do surface tension exists?
anything that has mass or takes up space
What is matter?
matter with a definite shape and volume
What is a solid?
liquid's resistance to flow
What is viscosity?
uneven forces acting on the particles on the surface of a liquid
What is surface tension?
matter that does not have a definite shape or volume
What is a gas?
vibrate, free to move, all directions
Describe the movement of particles within solids, liquids, and gases.
liquids and solds share volume, and liquid and gases share no definite shape
Name the property that liquids and solids share. What property do liquids and gases share?
A scientist places 25mL of a yellow substance into a 50mL container. The substance quickly fills the entire container. Is it solid, liquid, or gas?
the ability to do work or cause change
What is the basic definition of energy?
the energy of motion
What is kinetic energy?
the total kinetic energy of all the particles in a sample of matter.
What is thermal energy?
the movement of thermal energy from a substance at a higher temperature to one at lower temperature
Define the term heat.
the change from the solid state to the liquid state.
the change from the liquid state to the solid state.
vaporization (evaporation and boiling)
the change from a liquid to a gas.
as a gas condenses to a liquid it releases the thermal energy it absorbed to become a gas.
when the surface particles of the solid grain enough energy to become a gas.
when a gas turns into a liquid.
because its the energy of motion and particles within matter are in constant motion
How is kinetic energy related to the motion of particles and the state of matter?
the intensive property of the substance
What does temperature have to do with kinetic energy?
liquid CHANGES TO GAS forming bubbles in the liquid that rise to the surface
the change from a liquid to a gas.
no definite shape, nor definite volume
no definite shape, but definite volume
definite shape and definite volume
if it is ice you can leave it out for a few minutes and it turns from a solid to liquid.
How do you change a solid into a liquid? Give an example.
gas turns into liquid from the particles in the air
How do you change a gas into a liquid? Give an example.
Give an example of LOW Viscosity?
Give and example of High Viscosity?
energy stored in an object due to its postion
occurs at extremly HIGH TEMP. found in stars, lighting and neon lights
Movement of thermal energy from a WARMER substance to COOLER one
energy an object has due to its motion
the sum of the KINETIC and POTENTIAL ENERGY of the particles in a material
measure of the average kinteic energy of the individual particles substance
particles found in a random arrangement ex. RUBBERr, GLASS, and PLASTIC
What energy change occurs during Condensation?
temperture, substance, same
During all changes of STATE, the________ of a ________ stays the _________.
energy, 1g, substance 1C
Specific HEAT is a measure of the amount of _______ required to raise ______ of a _______.
