In the microwave, heat transfer occurs through a process called dielectric heating, where the microwave radiation causes water molecules in the food to vibrate, generating heat. This heat is then transferred from the water molecules to the rest of the food, reheating it evenly and quickly.
In a microwave, electrical energy is transformed into microwave radiation, which excites water molecules in food causing them to vibrate and generate heat through friction. This heat then cooks or heats up the food.
Convection is an energy transfer process that occurs only in fluids like liquids and gases. It involves the transfer of heat through the movement of the fluid itself, which results in the circulation of the fluid and the transfer of heat from one place to another.
The form of energy transfer that occurs when heat is transferred from one object to another is called conduction.
Convection is the type of heat transfer that occurs in only liquids and gases. It involves the transfer of heat through the movement of the fluid molecules due to differences in their density and temperature.
Radiation is the type of heat transfer that occurs in the form of waves. This transfer of heat can occur through empty space and does not require a medium. Examples include sunlight and heat transfer from a fire.
You will have experienced the impossible.
Microwave Radiation is Very Effectively absorbed by Water molecules, this results in the increased thermal agitation of the Water molecules that absorb the Mw radiation - as found in Microwave ovens.
electical energy is transform to heat energy
normally the oxygen transfer from the lungs to the cells through haemoglobin in most of the animals. the oxygen transfer occurs in lungs from the atmospheric air.
