Specific heat capacity of solid ethanol is 2.419 J/g C. Melting point temperature of ethanol is -114.4 C/ 158.8 K. Enthalpy of fusion of ethanol is 106.4 J/g. Specific heat capacity of liquid ethanol is 2.440 J/g C. 44.0 g of solid ethanol at -134.4 C is dropped into a Dewar flask containing 325 g of ethanol at -82.5 C. How much energy is transferred from the liquid ethanol to the solid ethanol to raise its temperature from -134.4 C to its melting point temperature, -114.4 C?
