Question
Chapter 13.2, Problem 22SSC
To determine
Reason as to how does sponging off the baby with fever with a liquid that evaporates easily helps.
Expert Solution & Answer
Answer to Problem 22SSC
Rubbing alcohol helps because alcohol evaporates easily.
Explanation of Solution
Introduction: A cooling effect is created on the body surface due to the evaporation process. The liquid which has weak cohesive forces, the particles of that liquid easily break and cause evaporation.
Cooling takes place due to evaporation. It is a natural phenomenon. According to the question, the doctor suggested (in the past) to sponge off the baby who had a high fever with alcohol because it evaporates easily as it has weak cohesive forces. The heat energy is taken away by particles or molecules during the conversion of liquid into gas. In alcohol, there is a very noticeable evaporative cooling effect.
Hence, it results in cooling down the temperature of the body.
Conclusion: Alcohol vaporizes faster than water. Thus, it can reduce the body temperature quickly and the baby will feel relaxed.
