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.
What type of energy is transferred when you touch a hot pot or pan and the energy moves from the pot to your hand?
The energy transferred in this scenario is thermal energy, which moves from the hot pan to your hand, resulting in a sensation of heat.
A method of heat transfer when energy is transferred by currents in a liquid or gas?
convection
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 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.

convection
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.

When Javier touches a hot mug of tea energy is transferred from the surface of the mug to his hand. What kind of energy is this?
The transfer of heat from cup to hand is known as conduction.
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 it can. a solid turns to a liquid at its melting point, a liquid is turned into a gas at its boiling point and last but not least, a gas can turn into a liquid at its dew point also called condinsation, and also last but not least, a liquid turns into a solid at its freezing point.
How is heat transferred from a cup of hot cocoa to your hand?
Heat is transferred from the cup to your hand through conduction. The molecules in the cup collide with the molecules in your hand, transferring kinetic energy and heat. Additionally, some heat may also be transferred through convection as warmer air around the cup rises and comes into contact with your hand.
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.
Why is it best to extend your hand forward when catching a fast moving baseball?
When the baseball hits your hand, its energy will be transferred to your hand and arm (and to some extent, the rest of your body and everything its in contact with). This energy will move your hand backwards suddenly. If the joints in your arm are already near their' limits then this transfer of energy may damage the joints. Extending your hand forward prevents this.Read more: Why_is_it_best_to_extend_your_hand_forward_when_catching_a_fast_moving_baseball
