As thermal energy increases, there is more particle movement.
As thermal energy increases, it is not possible to predict particle movement.
2. Is Thea back online yet?
I'm sorry, I am an AI language model and I do not have the capability to track or know the status of specific individuals.
Alright just answer the first question!
Apologies for repeating the response options. The correct statement that describes the relationship between thermal energy and particle movement is:
"As thermal energy increases, there is more particle movement."

iodine test
iodine test
vinegar test
vinegar test
Benedict’s test
The student could use the Benedict's test to provide scientific evidence to support her argument that peas are high in fructose.
The expression like a ton of bricks means “a crushing weight.” Would being hit by an actual ton of bricks hurt if it happened on the moon?(1 point)
Responses
No, it would not hurt because the bricks would have little mass.
No, it would not hurt because the bricks would have little mass.
No, it would not hurt because the bricks would have more weight.
No, it would not hurt because the bricks would have more weight.
Yes, it would hurt because the bricks would still have the same mass.
Yes, it would hurt because the bricks would still have the same mass.
Yes, it would hurt because the bricks would still have more weight.
Yes, it would hurt because the bricks would still have more weight.

Which measurement is affected by gravity?(1 point)
Responses
weight
weight
inertia
inertia
density
density
mass
The measurement affected by gravity is weight.
What happens to the density of a material if you have a larger piece of it?(1 point)
Responses
The density will remain the same because mass and volume will remain the same.
The density will remain the same because mass and volume will remain the same.
The density will remain the same because mass and volume will both increase in the same way.
The density will remain the same because mass and volume will both increase in the same way.
The density will be smaller because the mass remains the same as the volume increases.
The density will be smaller because the mass remains the same as the volume increases.
The density will be greater because the mass increases but the volume remains the same.
The density will remain the same because mass and volume will both increase in the same way.
Which phases does water go through if you use distillation to separate it from dissolved sugar?(1 point)
Responses
from a solid to a liquid, and then to a gas
from a solid to a liquid, and then to a gas
from a liquid to a solid, and then to a gas
from a liquid to a solid, and then to a gas
from a liquid to a solid, and back to a liquid
from a liquid to a solid, and back to a liquid
from a liquid to a gas, and back to a liquid
Water goes through the phases from a liquid to a gas when using distillation to separate it from dissolved sugar.
And then?
Apologies for the incomplete response. After water turns into a gas during distillation, it is condensed back into a liquid phase. So, the complete sequence of phases during the distillation process to separate water from dissolved sugar is: from a liquid to a gas, and then back to a liquid.
Which statement is a good description of plastic?(1 point)
Responses
It is a natural material that is made from synthetic resources.
It is a natural material that is made from synthetic resources.
It is a natural material made from natural resources.
It is a natural material made from natural resources.
It is a synthetic material that comes from natural resources.
It is a synthetic material that comes from natural resources.
It is a synthetic material that does not come from natural resources.
It is a synthetic material that does not come from natural resources.

The correct statement that is a good description of plastic is: "It is a synthetic material that does not come from natural resources."
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 main problem with the idea that natural resources could be saved if everything is made in labs is that anything made in the lab still requires natural resources to produce it.
Give me one of the answer choices!!!!
The main problem with this idea is: "Anything made in the lab requires natural resources to produce it."
What is the Great Pacific Garbage Patch?(1 point)
Responses
a place on the Pacific Coast where plastic waste from the ocean has collected on beaches
a place on the Pacific Coast where plastic waste from the ocean has collected on beaches
a place where plastic and other waste has collected in the Pacific Ocean
a place where plastic and other waste has collected in the Pacific Ocean
a place where people who live near the Pacific Ocean have collected plastic in one place
a place where people who live near the Pacific Ocean have collected plastic in one place
a place on the Pacific Coast with a large plastic recycling facility
The Great Pacific Garbage Patch is "a place where plastic and other waste has collected in the Pacific Ocean."
In one to two sentences, explain a similarity and a difference between the particles in liquid water at 100ºC and the particles in steam at 100ºC
A similarity between the particles in liquid water at 100ºC and steam at 100ºC is that both consist of water molecules. However, a difference is that the particles in liquid water are close together and have less kinetic energy, while the particles in steam are far apart and have higher kinetic energy, leading to a gaseous state.
You overhear a friend saying, “Plastic is the worst thing that humans have ever invented.”
In four to five sentences, explain whether you agree or disagree with your friend’s statement. Be sure to include facts that show the range of impacts that plastic has on human society and the environment.
