1. The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
2. Plants use photosynthesis to convert light energy from the sun to a more usable form during a process called energy transformation. The body takes the energy stored in food and converts it to a form that the body can use. This process is called cellular respiration.
3. (PLEASE STATE WHAT THIS THING IS CALLED. I'LL FOLLOW UP THE ANSWER AFTERWARDS IN THE COMMENT SECTION)
4. Electrical energy is supplied to the blender. This is converted into kinetic energy to turn the blades that blend the food, so energy is transferred from electrical to kinetic. This is the useful energy change that we most want to happen. However, not 100% of the electrical energy is transferred to kinetic energy. Some of the electrical energy is converted to sound energy (which is why blenders are noisy) and some is converted to heat (which is why you shouldn't leave them running for ages). These are less useful energy changes as they do not help to blend the food.
5. It can only change its form. In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).
