On a summer day, a scooter rider feels more comfortable while on the move than while at a stop light because
Option (A)
An object in motion captures less solar radiation
Option (B)
Air is transparent to radiation and hence it is cooler then the body
More heat is lost by convection and radiation while in motion
Air has a low specific heat and hence it is cooler
Correct Option:
Question Solution:
More heat is lost by forced convection as the value of heat transfer coefficient is large because it depends on fluid properties, velocity of flow and surface condition
