Sci reviewer ans key

Science Reviewer Answer Key:

Part 1: 1.) D Part 2: 1.) g Part 5: 1.) G = F = 300F
2.) B 2.) Fundamental Quantity R = K = ?
3.) D 3.) Force E = ( F – 32/ 1.8) + 273
4.) B 4.) Newtons S = (300 – 32/ 1.8) + 273
5.) C 5.) Area (268/ 1.8) + 273
6.) A 6.) cm2 (150) + 273
7.) D 7.) Derived Quantity A = 423 K = 4.23 * 10 2 K
8.) C 8.) cd
9.) D 9.) candela 2.) G = D = 13.5 g/ml
10.) D 10.) kelvin M of one soda = 4.5g
11.) A 11.) Volume R = V of all the sodas = ?
12.) C 12.) cubic centimeters E = (M of one soda * 6) / D
13.) D 13.) gm/ml S = (4.5 * 6) / 13.5
14.) B 14.) amount of substance (27) / 13.5
15.) C 15.) mole A = 2.0 = 2.0 * 10 0 ml
16.) B *16.) Fundamental Quantity
17.) A
18.) D
19.) D
20.) D
21.) B
22.) D
23.) C
24.) B
25.) A

Part 3: 1.) D – Using technology for peaceful/good purposes
2.) B - Scientific Attitudes
3.) A – Measuring instruments for mass
4.) D – Derived Quantities
5.) A – They all have 4 Sig. Figs.

Part 4: 1.) Reason = This assertion is unacceptable because according to the laws of scientific notation the number should be a mantissa meaning that the number should be less than ten but greater than or equal to one.
2.) Reason = This assertion is unacceptable because the unit name of volume is centimeters cube/ cubic centimeters/ cm3 and not centimeters squared.
3.) Reason = This assertion is acceptable because according to the “laws” of Significant Figures zeros that are mainly used for spacing is not counted as a sig. fig.
