change in state of matter -physics
how is the force of attraction in solids
strong
how is the state and volume of solids
definite
they can_____ in their position
vibrate
how does solids beocme iquids
by melting
how does melting works - solids
when we heat them up they gain energy and start vibrating ,which makes them weak,at a certain point called melting point they break their forces and turn into liquids
how is attraction in liquids
weak
they are free/ not free to move around
free
they have ____ volume
definite
when does liquid turn into gas
when they reach boiling point
how is force of attraction in gas
very weak
gas are ___ to move aroud
free
how is the volume and shape of gas
not definte
gas particles move in ______ line
straight
how to turn gas into liquid
condensing
how to turn liquid to solid
freezing
how does condenisng and freezing works
particels wont have enough energy to overcome teh forces so they will form more bonds
whats interanl energy
total enery stored by a particel that make up a substance or system
what happens when we heat up a substance
the substance transferes its energy to the kinetic energy stores of all teh particel ,so which increases their internal energy
how do we meausre the increase in internal energy of a substance
in temprature
what is tmerature of a substance
meausre of average internal energy of a substance
different substance have different specific heat capcity ,what is specific heat capcity
it is the amount of energy needed to increase the tempreature of a 1 kg of substance by 1 dgreee celsius
