The following diagrams show the particle arrangement in three different states of matter. Which diagram most likely represents the fastest moving particles?
There isn’t enough information to answer this question.
The law of conservation of energy describes how the amount of total energy can change in a closed system. Which of these statements correctly describes this law?
The amount of kinetic energy in a system is a constant value.
An object can have potential energy or kinetic energy, but not both at the same time.
Energy can be converted from one form into another, but it cannot be created or destroyed.
The amount of energy created when an object moves is equal to the energy destroyed when it stops moving.
Human activities involving fossil fuels can affect the environment in many ways. For example, drilling into land or the ocean floor can destroy habitats and pollute water and soil. Which of the following human activities does this example most likely describe?
using fossil fuels
obtaining fossil fuels
transporting fossil fuels
converting fossil fuels to usable forms
