What produces microwaves in a microwave oven?
Microwaves in a microwave oven are produced by a component called a magnetron, which converts electrical energy into electromagnetic waves that heat up food.
What do you call the molecules which make reactions work such as the breakdown of food molecules?
Enzymes are the molecules responsible for catalyzing biochemical reactions, including the breakdown of food molecules. They act as biological catalysts by lowering the activation energy required for these reactions to occur.
Why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food?
The total weight of a food item includes not only the weight of the nutrient molecules but also water, fiber, and other non-nutrient components. Nutrient molecules like carbohydrates, proteins, and fats only make up a portion of the total weight because they are typically smaller molecules that are densely packed with energy. This is why the grams of nutrient molecules in a food may not add up to the total weight of the food item.
What do we call a chemical that breaks down large molecules of food into smaller molecules of food?
We call the chemical that breaks down large molecules of food into smaller molecules "enzymes." Enzymes play a crucial role in the digestion process by catalyzing the breakdown of macromolecules like proteins, carbohydrates, and fats into smaller units that can be absorbed by the body for energy and nutrients.
Molecules which serve as chemicals to make reaction work- like the breakdown of food molecules?
They are called enzymes. They aren't necessarily considered molecules, but I suppose they are, perhaps very large ones. These enzymes act as a catalyst to speed the decompositions along. Stomach acid helps by oxidising the food as well as creating the environment for the proteins to function.
How microwaves cook food?
the microwave makes the water molecules in the food move and bump around this causes friction in the food to be cooked.
What property of microwaves makes them good for heating food?
Microwaves heat food by causing water molecules in the food to vibrate, creating friction and generating heat. This method is efficient and fast, as microwaves directly target and heat the water molecules in the food.
What ubstance in the food absorbs the microwaves?
Water molecules in the food. Microwaves work by only vibrating the water molecules, in order to increase the temperature of the food without significantly altering the properties of the food itself.
How do microwaves heat up food and what is the process behind it?
Microwaves heat up food by causing water molecules in the food to vibrate, generating heat. The microwaves penetrate the food and excite the water molecules, which in turn create friction and heat up the food. This process is known as dielectric heating.
How do microwaves heat food: from the inside out or the outside in?
Microwaves heat food from the inside out by causing water molecules inside the food to vibrate and generate heat.
What chemical in food absorbs energy from microwaves?
Water molecules
How do microwaves give off radiation?
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
Do microwaves cook food from the inside out?
Microwaves cook food by causing water molecules inside the food to vibrate, generating heat. This heat cooks the food from the inside out.
How do microwaves affect the water?
microwaves vibrate water molecules in food to create heat
How do microwaves heat food?
Microwaves heat food by emitting electromagnetic waves that cause water molecules in the food to vibrate, generating heat through friction.
What do microwaves do when they are used to heat food?
When microwaves are used to heat food, they cause water molecules in the food to vibrate rapidly, generating heat and warming up the food quickly.
What is a type of radiation that is absorbed by water?
Microwaves are a type of radiation that can be absorbed by water molecules. This absorption of microwaves causes the water molecules to vibrate and produce heat, which is why microwaves are effective for heating food and liquids.
