the cooker gives radiation waves to the food to heat it up
Heat travels quickly to the centre of food :)
Microwaves travel through the air or in some cases can also travel through glass, plastic, or ceramic materials. They are absorbed by food and liquids, causing them to heat up through the process of dielectric heating.
They travel in waves.
Rradiation is the only way that heat can travel in a vacuum.
Sound doesn't travel in heat. It travels in a physical medium.
Although some of the cooking in a grill is baking or roasting, the nature of grilling is radiation. To demonstrate that, put metal between your heat source and the meat and it will cook differently.
Some, but not all. Some materials are insulators- heat does not travel well through them.
Microwaves are a form of electromagnetic radiation that can travel through empty space and air because they do not require a medium to propagate. When microwaves encounter food, they excite water molecules which creates heat through friction, allowing them to cook food efficiently.
No, heat does not require a medium to travel. Heat can be transferred through conduction, convection, or radiation, and can travel through a vacuum as well.
Food waste does travel through the rectum.
Lets look at a vacuum and heat. Heat is the treansfer of energy from one piece of matter to another. A vacuum is the absence of matter. Heat cannot transfer in a vacuum because there must be matter in close proximity to other matter for heat to travel.
