Homework Statement
The rms speed of molecules in a gas at 20.0C is to be increased by 2 percent. To what temperature must it be raised?
Homework Equations
Vrms = Squareroot((3kt)/m)
The Attempt at a Solution
vrms.02 + vrms = squareroot((3kt)/m)
vrms(1.02) = squareroot((3kt)/m)
Too many unknowns.
In the solution manual it does
(vrms1/vrms2) = 1.02 = (squareroot t1)/(squareroot t2)
t2 1.02^2 = t1 then plug in 20 plus 275 for t2 to get t1
My miss understanding is how does the solution manual know its 1.02 as a portion?
They use proportionality or something. I can't see the logical steps.
Thank you
