Heat in liquid is primarily transferred via convection and conduction. Conduction is a short range force, it arises from the transfer of energy via molecular vibration. Convection is more to do with the motion of the liquid as a whole.
Conduction trasmits the heat from molecule to molecule, convection causes motion within the liquid due to hotter parts becoming less dense and rising.

Which is the fastest mode of transfer of heat?
The fastest mode of transfer of heat is conduction, where heat is transferred through direct contact between molecules in a material.
How is the energy transferred from the cooker to the liquid in the saucepan?
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 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.
What occurs when heat is transferred through liquid?
convection
Which is the fastest mode of transfer of heat?
The fastest mode of transfer of heat is conduction, where heat is transferred through direct contact between molecules in a material.
Heat can be transferred through a liquid by a process called?
Convection
What must happen to heat to be transferred to convection?
the liquid or gas must circulate to move the heat.

A method of heat transfer when energy is transferred by currents in a liquid or gas?
convection
Heat can be transferred without the requiement of a solid liquid or gaseous medium what is the name given to this form of heat transfer?
Radiant heat or Radiation
How is the heat transferred between the hot coffee and the part of the spoon that is in the hot coffee?
Heat will be transferred initially by conduction, which is the direct heat transfer between object (your hand and the liquid). If you leave your hand in long enough, convection will become a major factor. Convection is when currents from a liquid circulate to transfer heat.
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.
What are four ways in which heat can be transferred from one thing to another?
Heat can be transferred through conduction, where heat is transferred through direct contact between materials. It can also be transferred through convection, which involves the movement of fluids (liquids or gases) carrying heat. Additionally, heat can be transferred through radiation, which does not require a medium and can occur through electromagnetic waves. Finally, heat transfer can also occur through phase change, such as when a substance changes from a solid to a liquid or gas.
What three forms of heat energy can be transferred from a liquid in a thermos?
Conduction: heat transfer through direct contact between the liquid and the thermos. Convection: heat transfer as the liquid circulates within the thermos. Radiation: heat transfer through electromagnetic waves between the liquid and the walls of the thermos.
