uncertainty
1
Q
% uncertainty=
A
(uncertainty of measurement/ measurement) *100
2
Q
How do you calculate uncertainty for multiple readings ?
A
for change in temp , change in volume, mass,length you multiply their individual uncertainties by 2
3
Q
Quantum physics tells us measuring..
A
position , speed , direction precisely of an electron is impossible- called the uncertainty principle

Q
Each energy level has a different number of orbitals
A
that the electron could be in
