What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does heat affect diffusion?
Adding heat to a system will increase the rate at which something with diffuse in a fluid.
What happens to molecules from which heat is removed?
The molecules move slower when heat is removed.
What happens to heat when water evaporates?
Evaporation is an endothermic process and absorb heat.
What happens to the density of aluminum if you heat it?
it will melt
what is itcalledwhen Heatis removedfrom the systemand the particles slow down. Whenenough heat is removed, the particles nolonger haveenough speed to overcome the weakattractive forcesbetween them. Whenthis happens,the substanceenters its solidstate.?
Its solidifidation
What happens to the density of a fluid when heat is applied?
The density of a fluid goes down (becomes less dense) when heat is applied.
If you heat up a fluid what happens to the volume?
The volume will increase as the fluid is warmed up.
What happens if you heat semen in a microwave?
It will kill the sperm in the fluid called semen.
What happens to convection currents when the liquid or gas is no longer heat?
Nothing actually happens to convection currents when heat is no longer supplied. The currents are produced by applying heat, most often to the bottom. The warmed fluid is 'lighter' than the cold fluid surrounding so it rises to allow colder fluid to replace it and be heated. As soon as the heat is removed, all the fluid rapidly comes to a single temperature and convevtion does not happen! An opposite effect happens when cold air sits on the surface of a lake. In this case the water at the surface cools, gets 'heavier' and sinks. In this case the convection currents operates downwards.
How convection happens?
Convection happens due to the transfer of heat by the motion of a heated fluid such as air or water.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.

What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Is radiation the transfer of heat by the movement of a fluid?
No, most forms of radiation have nothing to do with heat. Transfer of heat by the movement of a fluid is called convection.
What is heat duty?
heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
A convection current transfers heat or air within a fluid?
a convection current transfers heat within a fluid.
