States of Matter
defined volume and a defined shape. The particles are close together, rigid, and vibrate. They hold their shape.
What is a solid?
the SI unit for pressure
what is a pascal?
change from a solid to a liquid
what is melting?
All matter is made up of atoms and molecules that act like tiny particles that are always in motion
What is kinetic theory?
no defined shape or defined volume. Their volume can change because the space in between their particles can change.
What is a gas?
defined volume but no defined shape. They slide pass one another and take the shape of their container.
What is a liquid?
an object will float or sink based on its_______
what is density?
Change from a liquid to a gas
what is evaporation?
the energy of motion from particles. measured my temperature?
what is kinetic energy?
the amount of force exerted on a given area of a surface
what is pressure?
most common state of matter in the universe like the stars
what is plasma?
when pressure increases volume decreased, when pressure decreased volume increases
what is Boyle's law?
what is freezing?
the measure of molecular motion
What is temperature?
two types of solids
what is crystalline and amorphous solids?
a no solid state of matter that include gas or liquids
what is a fluid?
constant pressure, volume of the gas increases temperature increases. Temperature decreases and volume increases
what is Charles law?
changes that require heat
what is endothermic changes?
mass cannot be created or destroyed only transformed
What is the law of conservation of mass?
energy cannot be created or destroyed only transferred
what is the law of conservation of energy?
has definite arrangement of atoms and a definite shape like diamond
what is a crystalline solid?
a change in pressure at any point in an enclosed fluid transmitted equally to all parts of the fluid
what is pascals principle?
turns directly from a solid to a gas
what is sublimation?
the total kinetic energy of all particles that make up an object
what is thermal energy?
the resistance of a gas or liquid to flow
what is viscosity?
