Give an example of heat transfer by convection?
An example of heat transfer by convection is when you boil water on a stove. As the water near the bottom gets heated, it becomes less dense and rises, while the cooler, denser water sinks to take its place. This creates a circulating flow of water, transferring heat throughout the pot.
When a pot of water is put on a stove the water at the top gets hot primarily by . a. radiation c. convection b. conduction d. condensation?
b. conduction - The heat is transferred from the stove to the pot, and then from the pot to the water through direct contact of the molecules.
How do the principles of convention conduction and radiation explain how the water in a saucepan gets hot?
Heat conduction occurs when the stove transfers heat to the saucepan through direct contact, causing the water to heat up. Heat convection takes place as the hotter water rises to the top and cooler water sinks to the bottom, creating a circulating flow that helps heat the entire body of water. Heat radiation also plays a role, as some heat is emitted from the stove and absorbed by the water molecules, further increasing their temperature.
What type of heat transfer is a boiling kettle on a stove an example of radiation?
No, boiling water in a kettle on a stove is an example of conduction - the heat from the stove directly transfers to the kettle, heating the water inside.
When water is boiled in a pan on a stove what energy is transferred?
When water is boiled on a stove, heat energy from the stove is transferred to the water. This heat energy increases the temperature of the water molecules, causing them to move faster and eventually reach a state of boiling where they turn into water vapor.

Why does the pan get hot?
what pan? if you are talking about on a stove its because the element on the stove gets hot when you turn it on and the heat gets transferred from the element onto the pan.

What is An example of heat transfer by convection.?
Water on a stove!
How do the principles of convection conduction and radiation explain how the water in the saucepan gets hot?
Convection: Hot water at the bottom rises, displacing cooler water, which then heats up and rises, creating a circulation that evenly distributes heat in the saucepan. Conduction: Heat is transferred directly from the stove to the saucepan, warming the metal of the saucepan which then transfers heat to the water in contact with it. Radiation: Heat from the stove is emitted as electromagnetic waves, which are absorbed by the saucepan and water, causing the molecules to vibrate and raise the temperature.
What happens to the temperature of the boiling water if you turn down the heat of the stove?
If you turn down the heat of the stove, the temperature of the boiling water will decrease. This is because the heat source is providing less energy to the water, causing it to cool down slightly.
How does water warmed up?
put it on the stove and it will heat up
how does heat reach water in a saucepan that is on a heated stove?
by boiling
Why would a gas stove have a hot burner when not in use?
a stove top is attached to the top of the oven.. the heat goes through. therefore it gets hot.
