A 200-gram liquid sample of Alcohol Y is prepared at -6°C. The sample is then added to 400 g of water at 20°C in a sealed styrofoam container. When thermal equilibrium is
reached, the temperature of the alcohol-water solution is 12°C. What is the specific heat
capacity of the alcohol? Assume the sealed container is an isolated system. The specific
heat capacity of water is 4.19 kJ/kg . °C.
