A chemist carefully measures the amount of heat needed to raise the temperature of a 1.21kg sample of a pure substance from 0.5C to 10.1C. The experiment shows that 10.kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 2 significant digits. Decide which intermolecular forces act between the molecules of each compound in the table below. Use the observation in the first column to answer the question in the second column. \begin{tabular}{|l|l} \hline \multicolumn{1}{|c|}{ observation } & \\ \hline At 20C, Substance A has a & 1 \\ vapor pressure of 83 . torr \\ and Substance B has a vapor \\ pressure of 113 . torr. \end{tabular}
