7. When 3,000.00] of heat are added to a 0.10 m long silver bar, its length increases by 5.00 x 10'4 m. What is the mass of the bar? Where a = 19 x 10'5/Cand c = 235 J/kg-C" Table 12.1 Coefficients of Thermal Expansion for Solids and Liquids Coefficient of Thermal Expansion (Co)-1 Substance Linear (ex) Volume (B) Solids Aluminum 23 X 10-6 69 X 10-6 Brass 19 x 10-6 57 X 10-6 Concrete 12 X 10 6 36 X 10-6 Copper 17 X 10-6 51 X 10-6 Glass (common) 8.5 X 10 6 26 X 10 6 Glass (Pyrex) 3.3 x 10-6 9.9 X 10-6 Gold 14 X 10-6 42 X 10-6 Iron or steel 12 X 10 6 36 X 10-6 Lead 29 X 10-6 87 X 10-6 Nickel 13 X 10-6 39 X 10-6 Quartz (fused) 0.50 X 10-6 1.5 X 10-6 Silver B =30 19 X 10-6 57 X 10-6 Liquidsh Benzene 1240 X 10-6 Carbon tetrachloride 1240 X 10-6 Ethyl alcohol 1120 X 10-6 Gasoline IIIIII 950 X 10-6 Mercury 182 X 10-6 Methyl alcohol 1200 X 10-6 Water 207 X 10-6 The values for a and & pertain to a temperature near 20 "C.
