What else can I help you with?
Is an Electric water heater conduction or convection?
The first: conduction from the solid heating coil
Is a pan over a flame radiation or conduction?
Both the flame heating the pan and the pan heating the water are examples of conduction. Convection is when the molecules of water heat other molecules of water.
What is a example of a convection but not conduction?
An example of convection without conduction would be the boiling of water in a pot. As the water heats up at the bottom of the pot, the hotter water rises to the top and cooler water moves downward to replace it. This creates a convection current that circulates the water, heating it evenly throughout the pot.
What are examples of heat transfers?

Which process transfers thermal energy by contact?
This proess is called conduction. The other processes are convection and radiation. Convection is the transfer of energy through movement, such as boiling water. Radiation is the transfer of thermal energy through a medium or space, such as the sun heating the earth.
How does convection and conduction affect stir fry vegetables?
In actual fact stir fry is both conduction & convection, this is because the food is getting hot by conduction But then it is convection as you generally put water or something in it.
What are examples conduction convection and radiation?
example of conduction is heating a metal rod. the heat transmits without the movement of particles. convection is heating water. example of radiation is the heat received by sun. in this case, heat travels through vacuum WITHOUT heating the space between the sun and the Earth.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
How do you beat conduction and convection radiation?
the form of heat transfer in which the energy is transferred from one molecule to another is called conduction. the mode in which the molecules get transported during the heat transfer process is called convention. heating up of sand is conduction and that of water is convention.
Differentiate the three methods of heat transfer?
Convection, radiation, and conduction are the 3 types of heat transfer... Compare They all transfer heat from a hotter mass to a cooler mass. Contrast Conduction transfers heat through solids. Convection transfers heat through liquids and gases. Radiation transfers heat through electromagnetic waves.
How do principles of convection conduction and radiation explain how the water in the saucepan gets hot?
In conduction, heat is transferred through direct contact between the heating source and the water molecules, causing the molecules to gain energy and increase in temperature. Convection occurs as the heated water molecules become less dense, rise, and are replaced by cooler water, creating a circulation that evenly distributes the heat. Radiation also contributes to heating by emitting infrared radiation from the heating source, which is absorbed by the water molecules, further increasing their kinetic energy and temperature.
What is convection or conduction in a hot water bottle?
Convection in a hot water bottle is the transfer of heat through the movement of the water inside the bottle as it heats up. Conduction is the transfer of heat through direct contact between the hot water in the bottle and the material of the bottle itself. Together, convection and conduction work to warm up the contents of the hot water bottle.
