a correct reason greater the flame more the heat will be transferred hence temp of water increases faster and hence it boils faster B correct Reason the external temp envolves the external heat in evopration of the sweat due to this the external heat doesnt reach the human body hence this process regulates the body temprature C correct Reason When you put your finger on an object that is colder than the surface of your finger heat energy will be transferred from the surface of your finger into the surface of the object until the temperatures are equalized by the process of conduction At the same time heat energy will be transferred from the interior of your finger to the cooling surface of your finger and heat energy will be transferred from the warming surface of the object into the interior of the object The rate of energy transfer will depend on the difference in See Answer
