Changes between Solids and Liquids
when the temperature of the ice reaches 0 C
the solid ice begins to change to a liquid
when the temperature of a gas becomes low enough
the gas changes to a liquid
particles are fast moving and spread out from each other
gases
as energy is transferred to a material
temperature increases when the state of matter is not changing
each substance has a unique...
melting and boiling points
while a substance is melting or freezing
the temperature remains constant until the change of state is complete
change of state from a gas to a liquid
condensation
particles are closely packed but can slide past each other
liquids
when temperature increases, kinetic energy..
increases
the more attracted these particles are, the more.... it takes to increase the distance
energy
substance changes between solid liquid
melting point or freezing point
overnight condensation of water vapor causes
dew
particles are closely packed and held in a rigid formation
solids
when a substance is changing state, the temperature stays the same at
the total energy of a system
thermal energy
the melting point and the freezing point are always the....
same for a given substance
the opposite of condensation
vaporization
the reason each state of matter has a different shape is because
of the particle attraction in each state of matter
when a substance is changing state, the potential energy...
increases
thermal energy depends on these 4 things
kinetic energy, potential energy, total number of particles, type of matter
when the ice changed into a liquid
the temperature remained constant
the first happens at the surface of a liquid, the second happens within a liquid
evaporation/boiling
stored energy due to the interactions between particles or objects
potential energy
when a substance is changing state, the distance between particles...
increases
the average kinetic energy of the particles
