Question

tracy makes a list of energy transformations that occur as an engine runs to power a car. 1. chemical energy transforms into thermal energy. 2. thermal energy transforms into electrical energy. 3. chemical energy transforms into gravitational potential energy. 4. thermal energy transforms into kinetic energy. which transformation should tracy remove from the list? 1 2 3 4

Explanation:

Step1: Analyze energy - transformation in a car engine

In a car engine, fuel (chemical energy) burns to produce heat (thermal energy).

Step2: Understand common energy - transformations

Thermal energy can be converted to kinetic energy to move the car, and some can be used to generate electrical energy for car systems.

Step3: Evaluate each option

Chemical energy directly transforming into gravitational potential energy does not occur in a car - engine operation. Gravitational potential energy is related to an object's height and mass, and there is no direct conversion from chemical energy to gravitational potential energy in a car engine.

Answer:

1. Chemical energy transforms into gravitational potential energy.
