Question
HW 6-part 1 (Due Friday, 03-09-18) 1. When you jump in a "cold" swimming pool. You feel that it is cold at the beginning, and then start to feel alright as time goes by. What changed in the process? Try to explain this in terms of heat flow rates given below. Q kA(T,-T,) Qover t is the rate of heat transfer - the amount of heat transferred per second, measured in Joules per second, or Watts. k is the thermal conductivity of the material - for example, copper has a thermal conductivity of 390, but wool has a thermal conductivity of just 0.04. Ti is the temperature of one object, and T2 is the temperature of the other. Since it's a temperature difference, you can actually use Celsius or Kelvin, whichever is most convenient. And d is the thickness of the material we're interested in.Explanation / Answer
As given
The heat flow depends on temperature difference between two bodies.With the time ,the temperature difference between pool water and body start decreasing so the heat flow rate also start decreasing so we experience comfortable after some time in pool
