Which flow diagram best explains the energy transformations that occur within an automobile running on diesel?
a) chemical energy → kinetic energy→ heat energy
b) heat energy → kinetic energy → chemical energy
c) kinetic energy → mechanical energy → heat energy
d) mechanical energy → heat energy → chemical energy

A) chemical energy → kinetic energy→ heat energy

Explanation:

Energy neither forms nor gets destroyed. Energy gets converted from one form to another. Diesel is a fuel which has chemical energy. When automobile starts running, the engine burns the fuel and it converts into kinetic energy with runs the automobile and the energy is converted to heat.

Hence, the correct sequence of energy transformation would be:

A)chemical energy → kinetic energy→ heat energy

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
