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.
How is energy transferred from a cup of boiling water?
Energy is transferred from a cup of boiling water through convection, conduction, and radiation. Convection causes the hot water at the bottom to rise, transferring heat to the cooler water at the top. Conduction transfers heat from the water to the cup, and radiation emits heat in the form of infrared waves.
How does energy transfers to water?
Energy can be transferred to water through various processes, such as heating, mechanical agitation, or electromagnetic radiation. When energy is transferred to water, it can cause the water molecules to gain kinetic energy, leading to changes in temperature, phase changes (such as boiling or freezing), or other physical and chemical changes.
2 Examples of thermal energy?
Boiling water on a stovetop - the heat from the burner transfers thermal energy to the water, causing it to heat up and eventually reach a boiling point. Solar panels converting sunlight into electricity - sunlight carries thermal energy, which is captured by the solar panels and converted into electrical energy for use.
When a kettle boils what are the energy transfers?
When a kettle boils, energy is transferred from the electric heating element to the water in the form of heat. The heat energy causes the water to increase in temperature until it reaches its boiling point, at which point some of the heat energy is also used to convert the water into steam.
What is an example of heat energy by convection?
An example of heat energy transfer by convection is boiling water in a pot. As the water is heated, the molecules near the heat source become less dense and rise, while cooler, denser molecules flow in to take their place. This creates a circulating flow of water that transfers heat throughout the pot.
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.
What happens when you mix ice water and saturated water?
Saturated water is water that's passed its boiling point yet hasn't evaporated yet. When putting ice water within this boiling-hot water, the heat energy from the boiling water transfers rapidly into the ice water, mixing the two and rapidly changing temperatures.
How is energy transferred from a cup of boiling water?
Energy is transferred from a cup of boiling water through convection, conduction, and radiation. Convection causes the hot water at the bottom to rise, transferring heat to the cooler water at the top. Conduction transfers heat from the water to the cup, and radiation emits heat in the form of infrared waves.
What happens to bacteria when they are boiled?
When bacteria are boiled the heat energy from the boiling water transfers through to the cells of the bacteria causing the water inside them to begin boiling as well. This increases the pressure inside the cells until they bursts, killing the bacteria. However boiling water will not have this effect on all bacteria.

What are the energy transformations for baking cookies?
It's convection, because an example of convection is water boiling,and when cookies is baking, the batter is really boiling.

What energy transformations occur in a stove heating a pot of water up to boiling?
In a stove heating a pot of water, electrical energy is converted to thermal energy as the stove’s heating element produces heat. The thermal energy transfers to the pot and water, raising their temperatures. As the water boils, some of the thermal energy is converted to kinetic energy in the form of water vapor.
What energy transfers are there when water freeze?
Heat
What are the waisted energy transfers of a kettle?
The wasted energy transfers of a kettle include heat loss to the surroundings due to poor insulation, energy used to maintain the water temperature once it has reached boiling point, and energy dissipated through the kettle's electrical components such as the heating element. These factors contribute to inefficiencies in the heating process and result in wasted energy.
