In order to fnd the specifc heat c of an unknown
substance, you place 75 g of the substance in a 30
g copper calorimeter that contains 65 g of water, all
initially at 20 °C. You then add 100 g of water at
80 °C, and measure the fnal temperature of the
system to be 49 °C. Assuming no heat is lost to the
environment, what is c? [Answer: c = 2200 J/kg.

- The Antoine Equation can be used to estimate vapor pressure at various temperatures for different substances using sets of empirically-derived constants. The equation can be written as: Where for water A = 8.07131, B = 1730.63, C = 233.426, T = temperature [°C], and P = vapor pressure [mmHg].
