The water which is hot rises to the top, and the cold water goes to the bottom to be heated. The heat transfers to the water, hence, making it hot. Then the hot water rises and the cold water goes down, then the heat transfers to the water and it carries on till all the water is fully heated.
What else can I help you with?
Use the word heat transfer in a sentence?
Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
Does a kettle use or produce heat?
A kettle uses heat to boil water. The heat is typically applied through a heating element in the kettle that warms up the water inside until it reaches boiling point.
What type of energy does a kettle use and what types of energy does it get converted to?
A kettle uses electrical energy and converts it into heat energy.
What energy does a kettle use to heat water?
A kettle typically uses electrical energy to heat water. When turned on, the electric current passes through a heating element in the kettle, which converts the electrical energy into heat energy that warms the water.
Marshmallow cooked by fire what heat transfer does it use?
When a marshmallow is cooked over a fire, it uses the heat transfer method of conduction. The heat from the fire is directly transferred to the marshmallow through direct contact, causing it to melt and cook.
Use the word heat transfer in a sentence?
Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
Which method of heat transfer use a medium?
Both conduction and convection require an intervening medium, but convection requires the medium to be able to move.
What method of heat transfer does a thermal camera use to detect an object?
A thermal camera utilizes radiative heat transfer to detect an object that is warmer than its surroundings.

What type of Heat transfer does a iron use?
An iron uses conduction as the primary method of heat transfer. Heat is transferred from the heating element inside the iron to the soleplate, which then heats up the fabric through direct contact.
How do you increase a kettle's efficiency?
To increase a kettle's efficiency, you can use a kettle that is the right size for your needs, regularly descale it to remove mineral buildup, and match the heat source to the kettle material. Additionally, keeping the kettle lid on while heating water and using an insulated kettle can help retain heat and improve efficiency.
What heat transfer method does a candle use?
A candle uses conduction and convection to transfer heat. The heat from the flame is conducted through the wick to melt the wax, which then rises as liquid and is heated further through convection as it is drawn up the wick and vaporizes to fuel the flame.
What type of heat transfer does a blow dryer use?
A blow dryer uses convection as the primary heat transfer method. As the heated air flows over the wet hair, it transfers heat through convection, helping to evaporate the water in the hair and dry it.
Why does a kettle have 800 watts?
Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.
