when water changes state from a liquid to a solid is energy absorbed or lost?

Answers

Answer:

Loses

Explanation:

liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.

Answer:

Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

What is the freezing point on this graph?

Answers

Answer:

Point a becuse it is the closest to -5*

Explanation:

Answer:

-5

Explanation:

Negative numbers get you confused.

- = Negative

5 = Number

You know 5 right?

I I I I I - 5

5 is a really less number already.

If you add a negative it will be double small.

Now lets figure out the problem:

What is the freezing point on this graph?

-5 is the smallest number

5 is bigger than -5

15 is bigger than 5 and -5

25 is bigger than all the numbers.

I know what your thinking. 25 is totally not the answer. Its the biggest number. Freezing is a very low number. What number is the lowest out of -5, 5, 15, 25. You see -5.

Therefore, -5 is freezing.

Gases ___ out and fill their container completely

Answers

Answer: Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed. Gases behave this way because their intermolecular forces are relatively weak, so their molecules are constantly moving independently of the other molecules present. Solids, in contrast, are relatively dense, rigid, and incompressible because their intermolecular forces are so strong that the molecules are essentially locked in place.

A. 4.5 seconds

B. 60.0 seconds

C. 90.0 seconds

D. 3.0 seconds

Answers

Answer:

The answer is option A

Explanation:

To find the time taken given the velocity and distance covered we use the formula

[tex]t = \frac{d}{v} \\ [/tex]

From the question we have

[tex]t = \frac{405}{90} \\ [/tex]

We have the final answer as

4.5 s

You crumple a piece of paper in your hands. Not all of the kinetic energy from your hands is used to crumple the paper. Where does the rest of the energy go?
A. It is transformed into sound energy.
B. It is transformed into light energy.
C. It is transformed into electrical energy. D. It is transformed into magnetic energy.​

Answers

Answer:

A

Explanation:

When you crumble a piece of paper it make a sound plus i just did on apex

When we crumple a piece of paper in our hands, a part of the energy is transformed into sound energy. Therefore, option (A) is correct.

What is sound energy?

Sound transmits through the medium such as liquids, gases, and plasma in the form of longitudinal waves or compression waves. It requires a medium to propagate as it can travel through solids as both longitudinal and transverse waves.

Transverse sound waves exhibit waves of alternating shear stress perpendicular to the direction of propagation while Longitudinal sound waves exhibit alternating pressure deviations leading to compression and rarefaction.

Generally, waves move matter up and down but do not carry along.  When we crumple the paper with our hands the kinetic energy of our hands is used to deform the paper but at the same time, we can listen to some sound which indicates that some energy is transformed into sound energy.

If a gold bar is 16,000 g mass and 800 cm^3 volume what is the density?

Answers

Answer:

The answer is 20 g/cm³

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 16,000 g

volume = 800 cm³

We have

[tex]density = \frac{16000}{800} = \frac{160}{8} \\ [/tex]

We have the final answer as

20 g/cm³

How can you tell if an element is a metal or a nonmetal??

Answers

Answer:

Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.

Explanation:

Answer:

looking at its metallic luster

Explanation:

Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements. Most elements are metals.

200.7 pm = _________________________nm

8.280 μg = __________________________pg

Answers

Answer:

0.2007 nm

3.57 cm

0.01478 g

8280000 pg

Explanation:

1)200.7 pm

1 picometer is equal to 0.001 nanometer.

1 nm = 1000 pm

200.7 pm× 1 nm / 1000 pm  = 0.2007 nm

2)0.000357 hm

1 hectometer is equal to 10,000 centimeter.

1 hc = 10,000 cm

0.000357 hc× 10,000 cm / 1 hc = 3.57 cm

3) 14.78 mg

1 gram is equal to 1000 milligram.

1 g = 1000 mg

14.78 mg × 1 g/1000 mg = 0.01478 g

4)8.280 µg

1 microgram is equal to 10⁶ picogram.

1 µg = 1000000 pg

8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg

Two hydrogen molecules per oxygen molecule are produced because water (H2O) has a ratio of two hydrogen atoms to one oxygen atom. A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.

H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. Water is chemical substance with no smell, taste or color.
