Conduction. The pan rests on the cooker top. Heat passes by direction conduction to the metal of the pan, and from the pan to the liquid.

Energy is transferred from the cooker to the liquid in the saucepan through conduction, where heat is transmitted from the hot surface of the cooker to the bottom of the saucepan by direct contact. This heat is then transferred to the liquid through convection, as the hot liquid rises and circulates, creating a convection current that heats the entire volume of liquid.

How will energy be transferred from your hand to liquid?
Energy transfer from your hand to liquid occurs through conduction when your hand comes in contact with the liquid. Heat from your hand is transferred to the liquid molecules, increasing their kinetic energy and raising the temperature of the liquid.
A method of heat transfer when energy is transferred by currents in a liquid or gas?
convection
How is energy transferred when there is a change of state?
When there is a change of state, energy is transferred in the form of either heat or work. For example, when a substance changes from a solid to a liquid, energy is absorbed to break the intermolecular forces holding the solid together. Conversely, when a substance changes from a gas to a liquid, energy is released as the substance condenses.
How is heat energy transferred through liquids?
Heat energy in liquids is primarily transferred through convection. As the liquid is heated, the molecules gain energy and move more quickly, causing them to push aside cooler, denser molecules. This forms a convection current that circulates the heat throughout the liquid.
Can energy be transferred from form to another?
Yes, energy can be transferred from one form to another. This is evident in processes like the conversion of electrical energy to light in a light bulb or the transformation of chemical energy into thermal energy during combustion.

Thermal energy transferred by circulation of liquid or gas is called?
Convection is the thermal energy transferred by the circulation of liquid or gas. It involves the movement of particles within the fluid, carrying heat energy from one place to another.

Why can forces be transferred in a liquid?
Forces can be transferred in a liquid because liquids are considered to be continuous and deformable materials. When a force is applied to one part of a liquid, it causes the liquid molecules to transmit the force throughout the entire liquid volume through pressure. This allows the force to be transferred from one point to another within the liquid.
In example of holding ice where does thermal energy go?
When you hold ice, the thermal energy from your hand is transferred to the ice through conduction. This causes the ice to melt and increase in temperature. The thermal energy does not disappear but is transferred from your hand to the ice, leading to a phase change from solid to liquid.
How is energy transferred during freezing?
During freezing, energy is transferred from the substance being frozen to its surroundings. As the substance loses heat energy, its temperature decreases until it reaches the freezing point, at which point it transitions from a liquid to a solid state. This transfer of energy continues until the substance is completely frozen.
What happens to the molecules that cause the thermal energy to be transferred?
In a material, such as a solid, liquid or gas, the molecules that carry thermal energy transfer their energy to neighboring molecules through collisions. As a result, the thermal energy is transferred from regions of higher temperature to regions of lower temperature until thermal equilibrium is reached.
What effect does liquid nitrogen have on molecular kinetic energy?
Liquid nitrogen decreases the molecular kinetic energy of substances by lowering their temperature significantly. The cold temperature of liquid nitrogen slows down the random motion of molecules, reducing their kinetic energy.
Which type of energry is being transferreed during phase change?
During a phase change, the energy being transferred is primarily in the form of latent heat. This is the energy required to change the state of a substance (such as from solid to liquid or liquid to gas) without changing its temperature.
