00:01
So here if we see what is happening here, here in this case, the temperature here, the temperature here in this case, it is 300 degrees centigrade.
00:10
And here it is we can say 273 plus 300 that will be equal to 573 kelvin.
00:18
It is the temperature here.
00:19
Here, so we can say the speed of the sound, we can say.
00:24
Speed of the sound, it can be written as v sound here.
00:27
In this case this we sound it is root under root gamma r t divided by the m so here this thing it is considered here for this case so now first of all we are considering this n2 gas and to gas it is considered here first of all so what is happening here nitrogen is a diatomic gas nitrogen it's a diatomic gas so what is happening here as it's a diatomic gas the gamma for this it is 7 divided by the 5 so here we can say the v it is the 7 divided by the 5 rt divided by them so from here v it is coming out to be 488 0 .05 meter per second so this is the v here so further what we can say in this so further for the hydrogen we can say the hydrogen which is here the hydrogen gas which is here in this case it is like this for the hydrogen the thing which is here, v for the hydrogen, vh2, it is we can say 7, gamma h2, it is 7 divided by the 5.
01:36
Mass it is 2 gram.
01:38
So, velocity for the hydrogen, it is 1 826 .12 meter per second.
01:43
So this is the velocity for the hydrogen in this particular case.
01:48
So this thing is considered here.
01:50
So further what is happening here? here, helium it is a monoatomic gas...
