It increases the surface area of blood that is exposed to the environment, which means there is a greater heat transfer capacity - meaning heat transfer is increased.

How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.
What method of heat transfer is known as conduction?
No,the transfer of heat by the movement of heated fluid is called convection.
By which mode of heat transfer heat is transferred in solids?
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
What is the heat transfer mechanism responsible for the daily wind cycle?
heat transfer through convection.
Does exothermic process absorb heat?
an endothermic process requires heat in order for the reaction to proceed in the forward (usual) direction. So it involves the use of heat as energy to initiate as well as continue the reaction
What temperature is required to transfer waste heat to the environment for an heat engine to be 100 percent efficient?
273k
Why impingement baffle is introduced at the shell side inlet of a shell and tube heat exchanger?
increase to heat transfer coefficent
What does the hole in the ozone layer cause to the environment?
massive heat increase, obviosly
How is heat energy lost through the body?
Heat energy in the human body is transferred to the ambient environment. To accelerate this transfer evaporation of moisture, sweat, assists. Generally the heat transfer is by radiation, thermal diffusion and conduction.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does land affect the environment?
reduces biodiversity, increase heat changes hydrology loss of trees increase in foreign species.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
How can heat transfer be promoted?
Answer is within heat transfer equationconduction = (k.A.dT/x)dtConvection = (h.A.dT)dtRadiation = s.e.AdT4.dtIncrease of conductivity (k) or heat transfer coefficient (h) or area (A) or temperature difference (dT) or contact time (t) or emissivity (e) allow for higher amount of energy to transfer.Reduce of transfer distance (x) increase rate of energy transfer.Increase flow rate to boost convection heat transfer (fluid)Increase surface area of contact (solid - fluid)Design heat exchanger in counter current flow (fluid)Prolong retention time (higher contact time -> more heat can transfer)Change of heat transfer medium (better thermal conductor medium)Use of heat pump (promote higher temperature difference yield better heat transfer)Coat surface with black colour (higher emissivity promote radiation heat transfer)
How does urban land affect the environment?
reduces biodiversity, increase heat changes hydrology loss of trees increase in foreign species.
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.
Why heat the inoculating loop after each transfer of microorganisms?
It is necessary to heat the inoculating loop after each transfer in order not to cross contaminate the media you are working with. It is also needed to maintain universal sterile procedures in a laboratory environment.
