2. On a Reaumur temperature scale, the melting point of ice is O'R and the boiling point of water is 80 R. Derive the expressions (formula) for converting temperature on (a) Reaumur scale to Celsius scale; and (b) Reaumur scale to Fahrenheit scale; and (c) Reaumur scale to Kelvin scale.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. "Since liquids do not have fixed shapes, the coefficient of linear expansion is not defined for them
