Answer 9

A cold dish of ice cream can be considered a closed system for a very short period of time.

Which best explains this phenomenon?

A.
The ice cream will eventually gain heat and melt.

B.
The ice cream can be eaten.

C.
The ice cream can be many different flavors.

D.
The mass of the ice cream will change as it melts.

Answer 10

Well It Is Not (A) and Not (D)

so it leaves you with only (B,C)
Unless ice cream chan change flavors, I think you'll

Answer 11

B?

Answer 12

yup

Answer 13

Which information about the earth would be represented when a globe is used as a model?
Choose all answers that are correct.
A. the angle the sun hits the earth
B. the speed of rotation
C. the shape of the earth
D. the earth's tilt

Answer 14

I would think C or D but im leaning towards # (D)

Answer 15

wrong a or b

Answer 16

The answer is A for the ice cream question.

Answer 17

D is the best answer for the globe question. While C might be an ok answer, it's not the best because the Earth is not a sphere. It's an oblate spheroid, a "squished" sphere.

Answer 18

Which information about the earth would not be represented when a globe is used as a model?

Choose all answers that are correct.

A. the earth's magnetic field

B. the location of the earth's oceans

C. the location of the earth's continents

D. the earth's orbit around the sun

Answer 19

A and D.

Answer 20

Why has the model of the atom changed over time?
A. All models of the atom created by scientists are too simple.
B. All atoms are unstable and are continuously changing.
C. The model of the atom changed as scientists made more accurate observations.
D. The model of the atom changed over time because the atoms changed composition.

Answer 21

It's because of the way science operates through the Scientific Method, which means that science tends to be self-correcting, which leaves C as the correct answer.

Answer 22

Why might the model of the atom change in the future?
A. The components of an atom differ from atom to atom and scientists have not discovered all the variations.
B. The components that make up an atom can change over time.
C. As new discoveries about the atom are made, scientists must update the atomic model.
D. Scientists are not able to see the atom, so all atomic models are a guess.

Answer 25

Which of the following defines a universal law?
A. a principle that was in effect but no longer applies
B. a principle that is in effect everywhere at all times
C. a principle that is in effect everywhere most of the time
D. a principle that is in effect in some places at all times

Answer 27

The answer is (B) do a new page you will get in trpuble if the coc whatever thing sees you

Answer 28

The answer two questions above--"Why might the model of the atom change in the future"--is the same as it was for why the model of the atom has already changed: science improved its knowledge. So the answer is C.
