Both the flame heating the pan and the pan heating the water are examples of conduction. Convection is when the molecules of water heat other molecules of water.

Take two colour cloth. one must be light & the other must be dark.Keep the clothes under the sunlight. You will notice that the light colour cloth will be cool compared to the dark cloth. this is called radiation. take a pan with full of water & heat it. After some time put a steel spoon inside the pan & leave it for a couple of min. you will notice that the spoon will also be hot. this is called conduction.
Conduction: Ice cubes melt quickly on a hot frying pan Convection: warm air moves toward the poles Radiation: The sun bombards Earth with light
Conduction Conduction is the transfer through direct contact which leads to the vibration of atoms. An example of conduction is a frying pan on a stove.

When water is in a pan over a flame, the heat from the flame is transferred to the water through conduction. As the water molecules gain energy, they move faster, which causes the overall temperature of the water to increase. This process continues until the water reaches its boiling point and starts to evaporate.
Pans are placed over a flame and not on the side of the flame, because it is an energy transfer by direct contact called conduction. And as you can see, pans are usually made of metals, wherein metals are a good conductor of heat unlike wood, which is a poor conductor of heat.
This is an example of heat transfer through conduction. The heat from the stove is transferred directly to the metal pan through physical contact, causing the molecules in the pan to vibrate, which in turn increases the pan's temperature.
Cooking bibingka involves all three methods of heat transfer: conduction from the pan to the batter, convection as hot air circulates around the pan, and radiation as heat is directly emitted by the oven's heating elements.
The heat used for frying is transferred to the pan by conduction and radiation and is transferred to the fried object by conduction through the oil.
Conduction is the transfer of heat through direct contact between materials, like when a hot pan heats up your hand. Radiation is the transfer of heat through electromagnetic waves, such as the heat we feel from the sun.
Convection occurs as warmer water particles rise, transferring heat to cooler particles below. Conduction happens as the heat travels from the stovetop to the bottom of the pan, heating the water through direct contact. Radiation occurs as heat energy from the stove is emitted in the form of infrared radiation and warms the water and the pan.

Any of these.conduction: pan fryingconvection: boiled eggs, deep fat frying, making soupsradiation: broiling, grilling, toastingconvection & radiation: bakingradiation & internal conduction and/or internal convection: microwaveetc.
The predominant heat transfer mechanism used to transfer heat from the pan to the stove burner is radiation.
The three modes of heat transfer are conduction, convection, and radiation. Conduction: This is the transfer of heat through direct contact between objects. For example, when you touch a hot pan, heat is transferred from the pan to your hand through conduction. Convection: This is the transfer of heat through the movement of fluids or gases. An example of convection is when warm air rises and cool air sinks, creating a convection current. Radiation: This is the transfer of heat through electromagnetic waves. An example of radiation is the heat you feel from the sun, which travels through space without the need for a medium.
