*****************************
Hello Students,
in this video I tried to explain you about the MCQ's ECAT & MCAT
i will try to close these Mcq's as soon as possible.
Medical College Admission test (MCAT)
And
Engineering College Admission Test (ECAT)
Are the tests which include Biology, Physics, Chemistry and English.
These tests just only consist on MCQ's. So Students need much practice for their success.
This video includes :
Multiple choice questions related to
A. Number of Moles
B. Avogadro's Number
C. Molar Volume
D. Calculations of their numerical problems
E. Ion and its election calculations
And their solutions.
I hope you guys are enjoying my lectures, please stay tuned to have more and share these lectures with your friends to get benefits.
Best Regards
Waris Hameed

very beneficial mcqs ...thank you soo much sir
JazakAllah sir kindly make more
Here is playlist you can find mcqs of all chapters....
MCQ's of MCAT, ECAT, PPSC, FPSC, SSE, AND SUBJECT SPECIALIST Chemistry: ua-cam.com/play/PLdLpaXa0VEh8LeeVtH-beSdss6EeSfVqy.html
Sir liquids and solids py bi vedio upload kr dain
Sir g that's real very beneficial for me
Thanks sir
sie Q 11 ka Answer D all of above is right bcz it is mentioned in the ptb book that K depends upon same
no of moles at same pressure
Sr in question 19 , density of a gas is expressed in gm/cm^3 Hoga ??
Ye GM/dm^3 kyu Hoga , ap ye explain krdain thora
Density is commonly expressed in units of grams per cubic centimetre. You are right 👍
Good ho gea sir
sir plz make this video in Urdu again
Nice
Sir how can we find that whether a gas is ideal or not? (Reference Mcq 21)
The gas which obeys all gas laws are called ideal. If it denny even one law than it will be non ideal.
@@ChemistrybyWaris Sir we are given with 3 to 4 gases so is there any trick or something by which we can choose the one which is ideal as in MDCAT we need short tricks
There are different factors by which we can check ideality of a gas..... gas is considered ideal if its particles are so far apart that they do not exert any attractive forces upon one another. I will explain in evening time..... When I'll be free (whatsapp +923360001291)
gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
MashaAllah jinaab good
MOstly answers are wromg guys
I solve them and answers are right galat news ña orao
sir Charles law constant mean tou pressure bhi included ha
V directly propotional to Absolute temprature. Pressure and number of moles are constant. V = kT
k= V/T
It still its confusing you can ask your questions in comments
Sir is ki mjy b smj nhi aye ...
Sir no of moles to constant ha to to Charles law us pr kesy depend kry ga agr no. of moles pr kr rha ha to phir pressure pr kue nhi kr rha
SIR IN KY ILLAWA OR BHI AA SAKTAY HAIN
PLZ TELL
Koshish to yehe ke hy k har taraah ka MCQ attempt kren..... Mazeed apko koe questions ho to discuss kr lejyega
Bs thorre bhoat tabdeeli ho sakte hy
Sir graphs bna kr b wo pouch lety hn isotherm konsa ha , the behavior of fixed mass of an ideal gas wala graph btaye....
Sir un ki smj nhi ati...
wo b explain kr dain
Sir question#8 ka "d" ha answer
No 8 question ka answer b hoga cuz pressure increase ho rha hai and 1 atm barhny se kafi change aaty hai volume mein means volume kafi decrease hoga
Slam sir..
Sir In 9 Mcq when the pressure is increased molecules come closer so they will also occupy a significant volume. Isnt it?
yes it is so....!!
@@ChemistrybyWaris to sir option C b hoga na correct
Q.9 Gases deviate from ideal behaviour at high pressure. Which of
the following is correct for non-ideality?
(a) At high pressure, the gas molecules move in one direction only
(b) At high pressure, the collisions between, the gas molecules are
increased manifold
(c) At high pressure, the volume of gas becomes insignificant
(d) AT high pressure, the intermolecular attractions, become
significant
Betta is MCQ me c option ke statement ee galt hy... jessy ap pressure increase krty hen to volume significane o jaata hy ye ulat keh raha hy.....
good
