Question
A student states that natural resources could be saved if people made everything they need in labs. What is the main problem with this idea?(1 point)
Responses
Anything made in the lab requires natural resources to produce it.
Anything made in the lab requires natural resources to produce it.
There are not enough synthetic resources yet to make what people need.
There are not enough synthetic resources yet to make what people need.
People might think it is fine to waste a lot of the materials since they just came from a lab.
People might think it is fine to waste a lot of the materials since they just came from a lab.
The materials made in labs will still pollute the environment and destroy natural resources.
The question is asking about the relationship between thermal energy and particle movement. Specifically, it wants to know which statement correctly describes this relationship.
To determine the correct statement that describes the relationship between thermal energy and particle movement, we need to understand the concept of thermal energy and how it affects the movement of particles. Thermal energy is the total kinetic energy of the particles within a substance.
The movement of particles in a substance refers to the motion of individual particles, which can include translation, rotation, and vibration. When thermal energy is added to a substance, it increases the kinetic energy of the particles, causing them to move more rapidly and energetically.
Based on this understanding, we can determine that as thermal energy increases, there is more particle movement. The correct statement is: "As thermal energy increases, there is more particle movement."
