If a car does not produce heat or sound, and uses gas to go somewhere, what happens to the energy?
According to conservation of energy, what happens to the energy in the gas if it doesn't come out as heat or sound?

You are asking an improbable question. The energy in gas when burned MUST come out as heat and sound. It's chemistry, not physics that governs what comes out if you burn gas.

Acceleration of the car? Heating of the car? You can't just say "does not produce heat or sound" because that can't be true.
It is kind of like saying "A man falls 20,000 feet without being hurt, where does the energy go?" Well the first part only applies in the joke - "but the last foot to the ground killed him"

Gas is perfectly converted to kinetic energy (motion).
In reality, this will generate heat from friction as the car interacts with its environment, and sound as the moving vehicle pushes air.

Assuming it doesn't release radiant light or cause an internal chemical reaction, then 100% of the energy is used to make the car move forward. You've solved the gas crisis and will become a multi-billionare, if the oil companies don't kill you first.

assuming this question has an actual answer: I would say that the energy comes out as friction. but since friction produces heat.....
hmm...maybe the gas is converted to liquid? or static electricity?
I dont know. sound is one thing, but no heat? that's a good one.

It's energy goes into the movement of the car. Movement is kinetic energy.

Car weight x its displacement=the energy consumed
