@eureka.. yes

@abhirup.. we cant even multiply them... so this question woudl be vague then..

i think what it means is simple value wise multiplication..

consider PV =nrT

here T P intensive

so PT intense
P/T intense
P + T not defined
VdP/dT + PdV/dt = nr
dP/dT= (nr - PdV/dt) /V = T/P - P/V dV/dt

here the second term is extensive so dP/dT extensive i guess

ne way i ve not solved any problem based on these in iit syllabus

@abhirup.. we cant even multiply them

why can't we multiply them [7]

we can multiply mass and acceleration...na...

intensive is one which does not depend on the volume we consider extensive depends on the volume!........... Nishant Bhaiyya...hwz it.....[4][4][4]....[9][9][9].........

xy will be intensive

x/y will be intensive

x+y will be intensive

dx/dy will also be intensive....

I think this should be the answer...

why? becasue x is not a function of V
y is not a function of V

and so one..

wat ur telling seems correct
maybe ans is wrong but wat about dx/dy

greatvishal swami ·

the Q is frm allen test series

bhaiyaa...how can we add two variables if they are not identical physical quantities??

intensive is one which does not depend on the volume we consider

extensive depends on the volume!...........

sir am i rite with that velocity explaination????

62
Lokesh Verma ·

vishal lets see this way

x is iindependent of volume..

y is independent of volume

how can x+y depend on volume!! :O

I dont understand the logic!

which book is it from?

eureka123 ·

example for c.......
If we add 2 colors ,we get another color which is an intesive property[1]
Same for velocity too..........we have been doing this for 1 year in mechanics[1]

hw dx/dy is extensive.......it cant be.........

greatvishal swami ·

a b r rite but dx/dy is given extensive and i m not getin it

1
MATRIX ·

i think xy,x/y and dx/dy are intensive and x+y as extensive........so it should be a) and b).....
