The specific heat of alcohol is about halfthat of water. Suppose you have 0.5 kg of alcohol at the temperature 20 °C in one container, and 0.5 kg of water at the temperature30 °C in a second container. When these fluids are poured into thesame container and allowed to come to thermal equilibrium, (a) isthe final temperature greater than, less than, or equal to 25 °C? (b)Choose the best explanation from among the following:I. The low specific heat of alcohol pulls in more heat, giving afinal temperature that is less than 25 °C. II. More heat is required to change the temperature of water thanto change the temperature of alcohol. Therefore, the finaltemperature will be greater than 25 °C.III. Equal masses are mixed together; therefore, the final temperature will be 25 °C, the average of the two initial temperatures

Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.
