Answer:

there would be 4,300mL of diplaced water

for this all your expected to do is to add all of the volume in the containers together.

Answer:

Correct option d = Sublimation

Explanation:

We know that gases occupy more volume as compared to the solid and liquid. Gases occupy all the available space.

In given option option D is correct because,

Sublimation is the process in which solid is directly converted into the gaseous phase without passing through liquid phase. So when substances under goes sublimation they are converted into gaseous form and occupy more space.

Oher options are incorrect because,

Deposition involve the conversion of gas into solid. Thus volume decreased. This option is incorrect.

Option B is also incorrect because,

Melting involve the conversion of solid into liquid. Volume increased as compared to solid state but not as much like in case of gases.

Option C is also incorrect because,

Vaporization involve the conversion of liquid into gaseous form. Volume also increase in this case but the volume increase in case of sublimation is higher than in case of vaporization that's why this is also incorrect.

Answer:

The correct answer is D. Sublimation

Answer:

In fusion reactions, two light atomic nuclei fuse together to form a heavier nucleus and release a large amount of energy.

Alt. Answer:

Fusion is the process that powers the sun and the stars. It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy.

Answer:

Due to the specific heat capacity of iron, 0.444 J/(g·°C), is more than the specific heat capacity for lead, 0.160 J/(g·°C)

Explanation:

The given parameters are;

The metals provided to melt the ice and their temperature includes;

One kg (1000 g) of iron;

Specific heat capacity = 0.444 J/(g·°C)

Temperature = 100°C

1 kg (1000 g) of lead

Specific heat capacity = 0.160 J/(g·°C)

Temperature = 100°C

Therefore, the heat provided to the ice of mass m, and latent heat of 334 J/g at 0°C by the metals are as follows;

For iron, we have;

ΔQ = Mass × Specific heat capacity × Temperature change

ΔQ[tex]_{iron}[/tex] = Heat obtained from the iron by the ice

ΔQ[tex]_{iron}[/tex] = 0.444 m × 1000 × (100 - 0) = 44400 J

Heat absorbed by the ice for melting, H[tex]_l[/tex] = Heat obtained from the iron

∴ Heat absorbed by the ice for melting, H[tex]_l[/tex] = Mass of ice × Latent heat of ice

H[tex]_l[/tex] = Mass of ice × 334 J/g = 44400 J

Mass of ice melted by the iron = 44400 J/334 (J/g) ≈ 132.9 g

Mass of ice melted by the iron ≈ 132.9 g

For lead, we have;

ΔQ = Mass × Specific heat capacity × Temperature change

ΔQ[tex]_{lead}[/tex] = Heat obtained from the iron by the ice

ΔQ[tex]_{lead}[/tex] = 0.160 m × 1000 × (100 - 0) = 16000 J

Heat absorbed by the ice for melting, H[tex]_l[/tex] = Heat obtained from the iron

∴ Heat absorbed by the ice for melting, H[tex]_l[/tex] = Mass of ice × Latent heat of ice

H[tex]_l[/tex] = Mass of ice × 334 J/g = 16000 J

Mass of ice melted by the lead = 16000 J/334 (J/g) ≈ 47.9 g

Mass of ice melted by the lead ≈ 47.9 g

Therefore, mass of  ice melted by the iron, approximately 132.9 g, is more than mass of ice melted by the lead, approximately 47.9 g.

A change that produce matter with a different composition is a chemical change.

Explanation:

Your results would be effected because there is a possibility that the water and chemical substance added into the flask will combine, possibly creating a reaction, either making the solution stronger or weaker, or possibly just messing up your experiment in one go.

For example:

If I paint a picture, and I have a cup that I use in order to put paint in, but the cup is wet and I put my paint in it, my paint will become more liquefied due to the fact water has been added to it, messing the paint up.

Answer:

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question

mass = 45 g

density = 10 g/cm³

We have

[tex]volume = \frac{45}{10} = \frac{9}{2} \\ [/tex]

We have the final answer as

From the question

mass = 112 g

density of mercury = 13.6 g/mL

We have

[tex]volume = \frac{112}{13.6} \\ = 8.23529411...[/tex]

Answer:

The experimenter observed this experiment in a lab rather than natural world because it might be dangerous to the atmosphere if he does the experiment in the natural world and it was still an hypothesis so that's why he did it in the lab.

Answer:

Coastal regions are often affected by abrasion. What process would cause increased abrasion along a costalregion? Abrasion is physical weathering caused by water, wind and gravity. The coastal regions areaffected by abrasion due to large volumes of water and increasedwinds.

Answer:

Hydraulic action of waves

Explanation: Coastal abrasion occurs as breaking ocean waves containing a sand and larger fragments erode the shoreline or headland. The hydraulic action of waves contributes heavily.

Answer:

116 km/h

Explanation:

We know that km/h means Kilometers an hour. And if this is constant, then he will travel 116 km/h.

✅Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
