Is heat transferred from a microwave to the food is a example of conduction?
No. It is an example of radiation. The heat is transferred by microwaves, which are a form of electromagnetic radiation. Conduction occurs when two objects of different temperatures are in contact or when different parts of an object have different temperatures.
What 3 ways does the heat move?
Convection, flowing through a liquid or a gas, Conduction, a transfer that occurs between the contact between two objects of different temperatures, or Radiation, where heat is emitted from the surface of an object.
What occurs if two objects at different temperatures are in contact?
Heat travels from the hot object to the cold object. For example, the handle of a metal poker left for a long time in a coal fire will eventually become too hot to grasp with bare hands.
What occurs if two objects of different temperatures touch?
If the contact is good, then energy (heat) will pass from the object at a higher temperature to the one at a lower temperature until the temperatures of the two bodies are equal. This precludes cases such as a burning match stick touching a flammable object and such
How is energy transferred when object are in contact?
conduction occurs
How conductivity occurs?
Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object. As they collide, the faster molecules give up some of their energy to the slower molecules. The slower molecules gain more thermal energy and collide with other molecules in the cooler object. This process continues until heat energy from the warmer object spreads throughout the cooler object.
When does the conduction occurs too?
Conduction is the transferring of heat from one substance to another. Therefore, conduction usually occurs when one hot object comes into contact with another object that is not as hot.
Evaporation occurs when two fronts of widely different moisture levels meet?
Evaporation occurs at different temperatures for different substances. Evaporation is just the change of state of matter from liquid to gaseous.
