states of matter
what are the main states of matter
solids liquids and gases
how spaced are particles are in a liquid
packed almost closely together
what is thermal energy
the totaled kinetic and potential energy of all particles in an object or substance
melting is when
solid turns into a liquid
what is evaporation
the process where a liquid turns into a gas
how many types of solid are there
two types
how do particles in solid move
vibrate
what is temperature
measure of the average kinetic energy of the particles in an object or substance
frezing is when
liquid turns into a solid
what is condensation
the process where water vapor in the air changes into liquid water
what is crystalliane
soldis that are made up of crystals
what is diffrent to solid partiels and liquid particles
they are not fixed in place
you can increase the thermal energy of a substance by
heatting it
what is the freezing point of water
Celsius (0° C) or 32° Fahrenheit (32° F).
how does submaltion happen
when a solid absorbs heat energy, causing its particles to gain kinetice energy
what is viscosity
a ressicntance
how do particles in gas move
freely in all directions
faster
what is the melting point of ice
32°F (0°C) at standard atmospheric pressure
What change of state is liquid heating up into a gas
condensation
how are the particles in a crystalline arranged
in a repeating pattern
what two properties of a gas depend on its contanier
