A scalpel made of surgical stainless steel is sterilized by heating in a flame and then quenching in 175 g of ethyl alcohol. The
alcohol is initially room temperature, 23.7°C, warms to 38.6°C. The specific heat capacity of ethyl alcohol is 2.4 J/(g'K) Assuming
there is no heat lost to the surroundings, calculate the heat released by the alcohol.
