The correct statement about energy is:
Energy can be changed from one form to another.
To arrive at this answer, we need to understand the basics of energy and its properties. Energy is a fundamental concept in physics and is defined as the ability to do work or cause change. It exists in various forms such as thermal energy, electrical energy, mechanical energy, and more.
Statement 1: Energy can be changed from one form to another.
This statement is correct. According to the law of conservation of energy, energy cannot be created or destroyed but can only change from one form to another. For example, when a ball is dropped from a height, its potential energy is converted into kinetic energy as it falls, and eventually, some of the kinetic energy may be converted into thermal energy upon impact.
Statement 2: Energy can be classified as one of three types: potential energy, kinetic energy, and chemical energy.
This statement is not entirely correct. While potential energy and kinetic energy are two broad categories of energy, there are many other forms, such as thermal energy, electrical energy, gravitational energy, and so on. Chemical energy is a specific form of potential energy associated with the arrangement of atoms and molecules in substances.
Statement 3: Energy is destroyed when a car uses gasoline.
This statement is incorrect. Energy is not destroyed when a car uses gasoline. Instead, the chemical energy stored in gasoline is converted into kinetic energy and thermal energy as the car's engine burns the fuel. Some portion of energy may also be lost as waste heat during this conversion process, but energy is not destroyed.
Statement 4: Energy can be created in a power plant.
This statement is not accurate. According to the law of conservation of energy, energy cannot be created or destroyed. Power plants generate electricity by converting different energy sources like fossil fuels, nuclear reactions, or renewable sources like solar or wind, into electrical energy. However, they do not create energy; they merely convert it from one form to another.
