What states of matter do convection currents transfer heat?
usually gases, but sometimes liquids
What causes the transfer of thermal energy during convection?
The movement of matter during convection is what transfers thermal energy.The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.
What is transfer of thermal energy from one substance to another?
This is heating and cooling. Direct transfer from one solid to another is conduction. Transferring through fluids (liquids or gases) normally uses convection. and heat being projected through a space, usually as light or infra-red, is radiation.Heat is the term that defines something that transfers thermal energy efficiently.
What is convection in physical science?
Convection is when water warms and expands. As the heated water expands, it rises because when a substance is hotter, it is also less dense. When the hotter and lighter water rises and reaches its maximum height, it is the farthest away from its heat source. It is then cooled and becomes more dense, sinking back down towards it's original location. It is usually related to liquids.
When heat travels by conduction or convention it has to travel?
Heat conduction (or thermal conduction) is the transfer of internal energy by microscopic diffusion and collisions of particles or quasi-particles within a body due to a temperature gradient.Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow).So heat must travel by diffusion, movement of fluids, or both; concerning conduction and convection.

Energy is usually transferred in fluids by radiation true or false?
False radiation is the transfer of energy through space.

What is the difference between a restricted and unrestricted IP address?
An unrestricted IP address is one which is not restricted by time, transfer limits, filters, ect. A restricted IP address is one which is limited from performing certain functions. An IP address is usually restricted to ban a certain type of internet activity.

What does convection conduction and radiation have in common?
They are all a way of transfering energy - usually heat.
State and discuss the modes transfer of heat?
The modes of transfer of heat are: # Conduction # Convection # Radiation In Conduction, heat is transferred along the material by the vibration of molecules. The molecules, however, don't actually move from their positions. It is usually seen in solids only. Heat transfer in Convection is by actual movement of material molecules. It is seen in liquids and gases. Radiation is the mode of transfer which does not need any material medium. The transfer of heat is done by electromagnetic waves.

Energy is usually transferred in fluids by radiation?
No, the principle method of heat transfer in fluids is convection, as the most energetic molecules rise towards the surface and the least energetic sink. Radiation is most significant for objects which are very hot, even glowing.
What usually occurs in gases and liquids?
Convection
Why is it necessary to remove heat from engine?
Heat can be removed from engine in three different ways. · Conduction : transfer of heat through solid · Convection : heat transfer by movement of molecules of substance · Radiation : transfer across spaces as rays such as use of fins. But, in internal combustion engine, usually heat is removed by passing coolant through air passages around engine blocks through radiator which absorb the heat by air passing over the fins and through radiator core. Air flow is assisted by Fans
