Plain childish. I am studying IE and I am very good at mathematics. I just got my engineering week test results back and I will yet again pass Engineering maths with distinction. So grow up. Every engineer becomes an industrial engineer. Industrial Engineers just become IE's faster. No matter...
Hi
I think I finally got it. The new rms must be 500 m/s . .. . . . ?
Has to be.. If it is, it is actually simple and I actually feel silly that I was so blind.
But thanks a lot for your help and sticking it out
Right, thanks I really didn't see that last part (4PV)...
Anyway...
Here is another shot at it:
250 = sqrt(3RT/M), therefore
250 = sqrt(3PV/m)
62500m = 3PV
By doubling P AND V (4PV)
62500m 12PV
and then
15625 = 3PV/m <=> 15625 = 3RT/M <=>...
Hi thanks for sticking out for me...
So after sticking in RT = PV/n into v(rms) = sqrt(3RT/M) I get:
v(rms) = sqrt(3PV/m).
250 = sqrt(3PV/m).
Now somehow I need to get an expression where P and V is doubled..and I can't seem to get to that point :-(
...
if
62500 = 3PV/m...
Hi thanks for the replies.
But I still can't seem to get my head around this one.
Could you please elaborate on the last statement:
You have two equations: PV = nRT and V(rms) = sqrt(3RT/M). (and also the definition of n). Put those together to get one equation without T, and you'll...
Hi, I have a thermodynamics problem which I tried to solve but have no idea whether my attempt has been succesful. Here is the problem:
Initially the translational root mean squared speed of an atom of a monatomic
ideal gas is 250 m/s. The pressure and volume of the gas are each doubled...
