An energy conversion that takes place when you warm a cup of hot cocoa in a microwave is a transfer of heat from the microwave's microwaves to the hot cocoa.
Energy conversions take place inside your body's cells, specifically in the mitochondria, where food molecules are broken down to release energy in the form of ATP (adenosine triphosphate). This energy is then used to power various cellular processes and activities.
In a microwave, electrical energy from the power source is converted into electromagnetic waves (microwaves) which in turn generate heat energy by causing water molecules in food to vibrate and produce heat. So, the energy transformation in a microwave involves conversion from electrical energy to electromagnetic waves and then to heat energy.
In a microwave oven, energy is transferred from the emitter (which is technically a klystron) to the water molecules in the item being heated, which have a resonant frequency equal to that of the microwave emission.
The main energy conversion is from chemical energy stored in the battery to electrical energy. The electrical energy powers the light bulb to produce light and heat energy.
Electrical energy is converted into electromagnetic radiation, specifically microwaves, in a microwave oven. This radiation is then absorbed by the food, causing the water molecules in the food to vibrate and generate heat, which cooks the food.
the conversions are solar to chemical to light to heat

Combustion. The carbon-matter and oxygen combust, releasing CO2, N, and heat.
The use of radio are -- to move information from place to place, quickly -- to deliver energy into organic substances, such as with diathermy machines and microwave ovens
