What energy transformation occurs in the microwave?
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.
What are Energy transformations in a microwave?
The microwave undergoes a variety of energy transformations when you are heating food. Starting from electrical energy (obtained via the mains power point/wall socket), the energy is transformed into microwave/thermal radiation (electromagnetic radiation/energy). These 'microwaves' react with the water particles in the food and cause them to vibrate. The friction produced by these vibrations produces heat and ultimately cooks/heats up your food. However, there is some energy that is transformed into light (the light you see when the microwave is one), sound (that humming noise you hear when it's operating) and kinetic energy (the rotating disk inside the microwave). Energy is transformed from electrical to heat, sound and light (if the microwave has a light). Energy is transferred to the food via the process of convection.
What energy changes occur in a microwave oven?
In a microwave oven, electrical energy is converted into microwave radiation. This radiation excites water molecules in the food, causing them to vibrate and generate heat through friction. This heat then cooks the food.
Give 5 examples of energy transformation on the kitchen?
Electrical energy is transformed into heat energy when using a microwave to cook food. Chemical energy in gas is transformed into heat energy on a stove burner to cook food. Electrical energy is transformed into mechanical energy in a blender to mix ingredients. Potential energy in food is transformed into chemical energy through digestion in our bodies to fuel our activities. Light energy is transformed into heat energy in an oven to bake food.
What i the wasted energy of a microwave?
In a microwave, wasted energy can occur due to heat loss through the walls of the oven, inefficient conversion of electrical energy to microwave radiation, and energy not being absorbed by the food being heated. This can result in lower efficiency and longer cooking times.
What is activation enery?
Activation energy is the amount of energy that a chemical reaction requires to occur.
Does a microwave produce nuclear energy?
energy cannot be produced or destroyed, only transformed.
Does fermintation occur in order to release enery from the original glucose molecule?
It can, yes, if there is insufficient oxygen in the tissue.
When melting occur and what is it called?
Melting occur at the melting point. The solid is transformed in a liquid.

What always occur in a chemical change?
The reactants are transformed in products.
