electrical energy to mechanical energy
It uses Heat energy. Mechanical energy. And most of all, electrical energy.
Mechanical energy is converted to heat.
Mechanical energy can create thermal energy by doing work on a substance, such as compressing a gas, or by friction as in brakes on a vehicle, which get very hot under braking.
changes from heat energy to mechanical energy because the heat from the hot cocoa is heat energy and mechanical energy is when you move your hand to get the cup or when u drink the hot cocoa
Bubbles last longer in cool water because the cold water doesn't take energy from the bubbles

can you please clarify what you mean, do you mean that the front heater blows cold but the rear blows hot or do you mean that when the heating is on cold it blows hot? many thanks paul
Yes, in fact, it does. this is because the increased energy in the atoms of hot water form stronger bonds with each other, giving the bubbles more surface strength and allowing, more bubbles to form.

A hot wheels car has kinetic energy. This is the energy possessed by an object due to its motion. As the car moves, it has kinetic energy due to its velocity and mass.
A car engine converts the heat energy contained in the hot high-pressure gases in the cylinder into mechanical energy. The heat comes from the formation of chemical bonds between carbon and oxygen, and between hydrogen and oxygen, when the hydrocarbon fuel is burnt with the air in the cylinder at the top of each power stroke.
Chemical energy (stored in the bonds of the molecules). When it burns, a lot of that energy becomes heat and a lot of that heat gets converted to internal energy as the hot combusted gas products reach high pressure with increasing temperature. The pressure pushes the pistons (kinetic energy) which translates to mechanical energy, which moves the car - which has kinetic energy as it moves.
