how heat transfer plays an important role in real life?
Answers
Answer:
Heat transfer is an essential part of our daily lives . One essential heat transfer that everyone is familiar with, although maybe not understand its use, is sweating. We sweat when we play sports, run for the subway or train or lay on the beach. The human body regulates its heat through the largest organ of our body – our skin. In most cases, sweating is not required but when our body works out more and we start to sweat, the body applies the laws of physics very naturally. The evaporation of our sweat consumes energy (latent heat) which our body wants to get rid of in form of heat. This process helps our body to stay cool, no matter if it’s due to a high fever when we are sick or run a marathon. Preventing our bodies from sweating under such conditions can cause us to overheat.
