Question
A car engine converts chemical energy from gasoline into kinetic energy to propel the car forward. Which law of thermodynamics applies to this conversion?*First law of thermodynamicsSecond law of thermodynamicsThird law of thermodynamicsZeroth law of thermodynamics
Solution
The Second law of thermodynamics applies to this conversion. This law states that energy transfers or transformations are never 100% efficient and that some energy is always lost as waste heat. In the case of a car engine, not all the chemical energy from the gasoline is converted into kinetic energy to move the car. Some of it is lost as heat, sound, and other forms of energy.
