1) CH3CL arises from microbrial fermentation and is found throughout the environment. It is also produced industrially and is used in the manufacture of various chemicals and has been used as a topical anesthetic. How much energy is required to convert 92.5 g of liquid to a vapor at its boiling point, -24.09 "C? The heat of vaporization of CH3CL is 21.40 kJ/mol.
2) Which requires greater thermal energy to warm from 25.0 "C to 100.0 "C, pure water or an equal mass of pure ethylene glycol, CH2OH2?
3) A sample of glass beads weighs 34.5 g and are heated to 100.0 "C in a boiling water bath. They are poured into a beaker containing 100.0 g H20 at 25.0 "C. When thermal equilibrium is reached, the temperature of the glass and the water is 29.9 "C. What is the specific heat capacity of the glass?
