Step 1 of 3

Lecture 1 Notes ̊̊C+ 273.15 = K ̊̊C=5( ̊F-32)/9 2.54 cm = 1 inch 6.50 cm 1 inch 2.54 cm D=m/v Significant Figures Non zero digits are always sig Zeros are significant if b/w sig digits or at end of decimal point 0 at end of numbers that don't contain decimals have variable sig figs Exact number numbers of sig figs b/c no uncertainty Mult: use the least sig amount of sig figs in final number (i.e., if multiplying 2 by 3 sig fig, final answer has 2 sig figs) If digit removed is 5 followed by zeros, then the preceding number increases by 1 if odd, and stays the same if even Energy of electromagnetic radiation: directly proportional to frequency, inversely proportional to wavelength Bohr's equation determines energy needed to remove electron from H atom, difference b
