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.
When you warm up a cup of cocoa in a microwave oven, electrical energy is converted to electromagnetic radiation (microwaves) to heat up the water molecules in the cocoa. The absorbed radiation energy is then converted to thermal energy, raising the temperature of the cocoa.
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 boiler, the energy transfer that takes place is from fuel combustion to water in the form of heat. The fuel is burned, producing heat that is then transferred to the water to create steam. This steam can then be used for various applications, such as power generation or heating.
When something is dropped, potential energy is converted into kinetic energy as it falls due to gravity.
When steam enters a turbine housing, it undergoes a transfer of thermal energy into kinetic energy. This thermal energy causes the steam to expand and move rapidly, which in turn drives the turbine blades to rotate. The rotational motion of the turbine blades is then converted into mechanical energy that can be used to generate electricity or perform other types of work.

electrical energy into hat energy
exothermic!!
electrical energy into chemical energy
Your muscle energy converts to kinetic energy.
Mode of energy transfer in fluids is convection.
kinetic to electrical to sound
The basic idea is that electrical energy is converted into chemical energy, which is what the battery stores.
An adiabatic wall can be defined as a wall through which no energy transfer takes place.
