Homework Statement



pV=nRT dV=10cm^3/min dP=-0,3N/cm^2/min n=5mol V=100cm^3 P=2N/cm^2 where d is change.
how does tempperature(T) change( dT/t ) compared to time


The Attempt at a Solution



No idea

Consider expanding

d(PV)=d(nRT)

(use the product law on the left side)


I'll help you with the right side :)

d(nRT)=nR(dT)
 
So PdV+dPV=nRdT

dT=PdV+dPV/nR

dT=2*10-0.3*100/5R

dT=-10/5R ... ?
 

Thread 'Finding the nth roots of a complex number'

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
