What is Daltons law of partial pressure?
Daltons law of Partial Pressures states that the total pressure that is occupied by a mixture of gasses that are not chemically reacting with each other is equal to the summation of the partial pressures of the constituent gases in that mixture. In this video i get to explain the meaning of Partial Pressures plus daltons law

0:00:00.060,0:00:03.899
in today's session I get real estate
0:00:01.650,0:00:10.740
dalton's law of partial pressures coming
0:00:03.899,0:00:13.380
up in 1801 a scientist called John
0:00:10.740,0:00:16.500
Dalton is observed that when you put two
0:00:13.380,0:00:18.240
or more gases in a container each gas
0:00:16.500,0:00:20.279
contributes to the total pressure of the
0:00:18.240,0:00:23.250
entire gas if you look at that
0:00:20.279,0:00:26.099
illustration we are having this box and
0:00:23.250,0:00:28.170
didn't hear this gas a and gas B of
0:00:26.099,0:00:30.539
course when this took us is an inside
0:00:28.170,0:00:34.020
this container they are mixed up and
0:00:30.539,0:00:37.620
definitely as the molecules or is moving
0:00:34.020,0:00:43.140
around in that gas they inflict pressure
0:00:37.620,0:00:45.120
on these walls now let's assume that we
0:00:43.140,0:00:49.140
remove gas B and we live gasped
0:00:45.120,0:00:50.399
air alone or we remove gas a and gas B
0:00:49.140,0:00:53.480
remains there alone
0:00:50.399,0:00:57.870
if we remove gas B and a remains alone
0:00:53.480,0:01:00.359
it means it will be still in the same
0:00:57.870,0:01:03.000
container with the same volume but now
0:01:00.359,0:01:05.580
it will only because a inflicting
0:01:03.000,0:01:07.979
pressure on the walls of this container
0:01:05.580,0:01:10.350
likewise if we leave gas be alone in the
0:01:07.979,0:01:12.960
container and we remove cast a it will
0:01:10.350,0:01:14.970
only be gas B that will be remaining to
0:01:12.960,0:01:17.790
impose pressure on the walls of this
0:01:14.970,0:01:20.490
container now this amount of pressure
0:01:17.790,0:01:22.229
that I would exert if it is left alone
0:01:20.490,0:01:25.140
or the amount of pressure at buildings
0:01:22.229,0:01:28.470
that if it is left alone is what we are
0:01:25.140,0:01:30.990
calling partial pressure so by
0:01:28.470,0:01:34.140
definition partial pressure is the
0:01:30.990,0:01:37.229
pressure that would be exerted by a gas
0:01:34.140,0:01:39.060
if it feels the container alone I can
0:01:37.229,0:01:41.970
say partial pressure is the pressure
0:01:39.060,0:01:45.079
that a gas would exert if it feels alone
0:01:41.970,0:01:53.820
a container which was previously
0:01:45.079,0:01:56.100
occupied by a mixture of gases now that
0:01:53.820,0:01:58.560
we know what partial pressure means we
0:01:56.100,0:02:01.890
can now go ahead and start talking about
0:01:58.560,0:02:03.750
dalton's law of partial pressures now
0:02:01.890,0:02:07.110
dalton's law of partial pressure simply
0:02:03.750,0:02:10.470
states that if two or more gases are put
0:02:07.110,0:02:13.660
together in a container and that these
0:02:10.470,0:02:17.110
gases when in that container are not
0:02:13.660,0:02:19.300
chemically reacting together then the
0:02:17.110,0:02:22.390
total pressure of the mixture of those
0:02:19.300,0:02:25.240
gases is equal to the sum of the partial
0:02:22.390,0:02:28.300
pressures of the components in those
0:02:25.240,0:02:31.450
gases right here is our gas and in this
0:02:28.300,0:02:33.340
gas this is a mixture of the lesser this
0:02:31.450,0:02:36.490
is a gas it's having a mixture of gas
0:02:33.340,0:02:38.110
and gas B and these gases as they are
0:02:36.490,0:02:42.070
interacting they are not chemically
0:02:38.110,0:02:44.440
reacting with each other now the total
0:02:42.070,0:02:46.330
mixture
