Question

The energy transfers occurring in a car engine change chemical energy into ________ . I. kinetic energy II. sound energy III. heat energy

A. Only I
B. I, II, and III
C. I and II
D. I and III

Answer 1

B 1 2 and 3

Step-by-step explanation:

This is because the car produces noise when starting up an engine (sound energy), heat is definitely produced as result of starting it up (thermal/heat energy) and the engine itself begins to "move/vibrate" which then helps the car itself to move (kinetic energy)

Answer 2

C. I and II

Step-by-step explanation:

The energy conversion in a car engine is quite interesting.

It starts with chemical energy which is obtained by burning of gasoline in the engine. Burning gasoline releases a form of thermal energy which heat. The heat is converted into mechanical energy which causes the motion of the car by driving pistons. The chemical energy is a potential energy source.
