L5 : Extensive & intensive property - Thermodynamics, Class 11 Video Lecture

hello friends this video on
thermodynamics part 5 is brought you by
exam fear calm
no more fear from exam before watching
the video please make sure that you have
watched part 1 - part 4 discuss a new
topic or new property call extensive and
intensive properties will be using these
concepts to solve carbonize problem so
extensive property is something whose
value depends on the quantity or size of
the Marten present in the system example
mass volume internal energy enthalpy
these are extensive order and the
intensives are those whose a quantity
which do not depend in or depend on the
size of matter so they depend on the
size of matter they don't do anyone on
the size of matter size of my example
temperature and sleep restriction so let
me explain this so I had this big box
covered and let me suppose it's volume
is B its volume is V I'll take all know
its mass is M its internal energy is e
this enthalpy is little H we discuss as
demand calculator and heat capacity C
will take this value also or temperature
is T density is minus about this value
pressure is P let's talk about its
properties so there is a big job covered
totally and each has some gas whose
volume is V mass M internal energies e
in calm easy C is the specific heat
capacity C the heat capacity not
specifically discuss this terms or begin
ignore these now because we don't know
these values temperature density and
pressure so what if we divide this into
two different sections
now if you see the volume on this will
be what 3 by D and this will be what
Levi - the volume has changed the mass
will be mask button remember Wright
brothers divided talk about the energy
energy will also be divided but if you
talk about temperature temperature will
still be same for know you talk about
density it will be still the same for
both if you look what pressure pressure
will also be simple so if you see these
properties changed right and this
depends on the quantity of the matter
but these properties these properties
temperature pressure intensity means
then change I know what is the sample
didn't change the one in the server
didn't change they don't depend on the
quantity
so here the key is quantity of my so if
some property depends on the quantity of
matter that is my extensive property if
you increase the quantity the volume
increase increase equality the mass
increase increase avanti energy increase
is that extensive property property
which do depends upon the quantity of
they are intensive property for example
if you increase the quantity also the
fed temperature won't increase provided
the the quantities of the same note
impression if you increase the quantity
the density and the pressure markers in
this case you see these are extensive
and intensive properties thank you visit
