In a kettle, convection works by heating water at the bottom of the kettle. As the water gets hot, it becomes less dense and rises to the top, displacing the cooler water. This creates a circular flow of water as hotter water rises and cooler water sinks, leading to even heating of the entire volume of water in the kettle.
Yes, a kettle is an example of convection. When the water is heated at the bottom of the kettle, it becomes less dense and rises to the top, while cooler water flows in to replace it. This creates a convection current that helps evenly distribute the heat and boil the water.
In an electric kettle, the heating element at the base heats the water closest to it, causing this water to become less dense and rise towards the top. As it rises, cooler water from the top of the kettle moves downwards to replace it. This creates a circular motion known as convection currents, ensuring that the water heats up evenly.
Yes, boiling water in a kettle involves the process of convection. As the water is heated, it becomes less dense and rises to the top, while cooler water from the top flows down to replace it. This circulation of water is an example of convection.
Heat transfer in a kettle occurs through conduction. The heat from the stove is transferred to the bottom of the kettle, which then spreads throughout the kettle via conduction, causing the water inside to heat up. Heat is also transferred through convection as the hot water rises and circulates within the kettle.
The process of water boiling in a kettle involves convection primarily. As the water at the bottom of the kettle is heated, it becomes less dense and rises, while cooler water moves down to take its place. This creates a convection current that transfers heat throughout the water, causing it to boil. Conduction also plays a role as the heat is transferred from the kettle to the water through direct contact. Radiation is not a significant factor in this specific scenario.

Heat transfer from kettle wall is both convection and radiation but convection play the major role on the temperature below 100 oC. Air expand on contact of hot surface and float upward since it is lighter than surrounding air cause stream of air come into contact of the kettle surface result to rapid heat loss.

Heat travels through water in a kettle primarily through convection. In this process, as the water at the bottom of the kettle heats up, it becomes less dense and rises to the top, while cooler water near the surface moves down to replace it. This creates a continuous circulation of water, transferring heat throughout the kettle.
In an electric kettle, water becomes hot by using a heating element that heats up when the kettle is turned on. The heating element transfers heat to the water, raising its temperature until it reaches boiling point.
