When automobiles are designed, engineers try to maximize their fuel efficiency. Even with modern technology, today's most efficient vehicles can only attain about 30% efficiency. That means of all the chemical energy of the fuel put into an automobile, only 30% of the fuel results in car motion. Which statement best explains why this happens?(1 point)
