Problem Q21.6

Your clothing tends to cling together after going through the dryer. Why? Would you expect more or less clinging if all your clothing were made of the same material (say, cotton) than if you dried different kinds of clothing together? Again, why?

Find Rn as multiple of old resistance Ro Suppose electrical wire replaced w one having every linear dimension doubled  With higher T, atoms vibrate leading to thermal scattering of electrons  Electrons find it more diff to pass thru atoms bc of more collisionsw atoms  Increased e- scattering w inc T= inc R  For most metals, R inc approx linearly w T over limited T range    Ex) platinum resistance thermometer-measures T by measuring change in resistance of conductor ○ Principle of thermometer measured by resistance formula above ○ When device is immersed in vessel containing melti
