The event which most likely occurs at point V during a rock cycle is cooling.

Point V is present in the rock cycle, where changes in the state or nature of rock takes place.

When mangma comes towards the surface of the earth then due to change in temperature and pressure it will concerts into the igneous rock by cooling process and coverts into the harder form.

Hence at point V, colling is occur.

nswer: 959.67 K or 686.67 C

Explanation:

Entropy of Vaporization (S) = Heat of Vaporization (H) / T ( boiling point) (in Kelvin)

1.) Flip the equation to have T as the product --> T = H/S

2.) We need to change H from kJ to J --> 69.0 kJ/mol --> 69000J/mol

3.) Substitute numbers in the equation --> (69000 kJ/mol) / (71.9 J/Kmol) = T

4.) T = 959.67 K or in Celcius --> 959.67 - 273 = 686.67 C

Answer:

Energy is carried from one point to another or from one region to another by moving mass or through the action of waves.

· All waves have a source.  This source transforms energy into forms that can be carried as waves.

· Waves are not material objects.  Waves represent the moving energy being carried away from the source.

Waves are coordinated vibrations that transport energy.  Sometimes waves require the vibration of particles in matter to move, other waves travel without any need for particle vibrations.

Explanation:

Wave energy requires no motion for its movement whereas matter energy requires motion. Wave energy travels in electromagnetic spectrum whereas this is not applicable to matter energy.

Wave energy is obtained from the water currents in the ocean and seas. The energy so harnessed is a renewable form of energy.

Wave energy is important as it provides enormous energy harvest. Waves have the high potential to generate energy on a mass scale. This energy can be utilized for energy production, water desalination etc. Special wave energy converters are available for this purpose.

Wave energy will reduce the dependence on fossils for energy. It can be considered as a reliable source to obtain energy using wave power. However, it is an expensive way and also requires high maintenance.

Wave energy is also weather dependent. As disturbances in the weather affect the energy production.

Thus, waves can be considered as an important source of renewable energy on earth.

Answer:

The feedback mostly on the scenario mentioned is defined downwards.

Explanation:

There seem to be forces that regulate the whole mechanism as well as preserve equilibrium in every natural cycle. It is possible to divide these variables into two simple types:

The improvement throughout the natural state is attempted by negative factors as well as the positive reinforcement attempts to mitigate this improvement and approach the problem to something like the primary comfortable position.

Let's take a basic example including its process for suggestions. Users start whimpering if you get too cold. Your body continues to pump additional blood attributable to the whole shivering and indeed the temperature therefore raises. Throughout this circumstance, the temperature drop is a mechanism that serves to initiate the shivering, as well as the shivering attempts to recover the steady body’s temperature. Therefore the shivering case seems to be positive feedback that seeks to restore the primary balance.

Much the same for the landmass uplifting allows the emergence of more life above it. So, social advancement seems to be a system of negative criticism that disturbs the equilibrium. After that, the main elevation of the landform needs to regain the excess volume of degradation. So, this is indeed a tool for constructive feedback.

The new concentration of the solution is 0.016 M

From the question, we are to determine the concentration of the new solution prepared from question 4.

NOTE: Question is provided below

From question 4, the concentration of the sodium chloride solution is 0.200M

Now, to determine the new concentration,

Using the dilution law

C₁V₁ = C₂V₂

Where

C₁ is the initial concentration

V₁ is the initial volume

C₂ if the final concentration

and V₂ is the final volume

Then,

C₁ = 0.200 M

V₁ = 10.00 mL
C₂ = ?

V₂ = 125.00 mL

Then,

0.200 × 10.00 = C₂ × 125.00

[tex]C_{2}= \frac{0.200 \times 10}{125.00}[/tex]

C₂ = 0.016 M

Hence, the new concentration of the solution is 0.016 M

The concentration of the NaOH in the solution will be 0.5 mol/L

The concentration is defined as the amount of a particular chemical present in the mixture.

Now the given chemical reaction is:

2NaOH + H₂SO₄ = Na₂SO₄ + 2H₂O

The volume of (H₂SO₄)=0.25 L

The concentration of (H₂SO₄)=2.00 mol/L

The volume of (NaOH)=2.00 L

Now the concentration will be calculated as:

[tex]c(NaOH)= \dfrac{2c(H_2SO_4)}{v(NaOH)}[/tex]

[tex]c(NaOH)=\dfrac{2\times2\times 0.25}{2} =0.5\ \frac{mole}{L}[/tex]

Hence, the concentration of a solution of NaOH is 0.5 mol/L

Good luck everyone, you got this! Have a great day!

Answer:

We have a chemist who collects 59 ml of S. 0. 2 at the pressure atmospheric pressure. Also, this one is considered as proven. We one and this one is pretty even so this is 0.989 atmospheres. Now is the second day the pressure atmospheric pressure was 0.967 atmospheres. Then what is the pressure of sulfur dioxide in the flask? Oh, so if you see here, we know that the one we want is equal to P two. We do so from the ideas equation. So this one is equal to what we want we do so we do is equal to P one. We want we do. Then it is equal to P one is 59 B one and B one is 0.989 and debated by 0.967 atmospheres. So this one is atmospheres and atmospheres and this one is Ml. So here the 0.967 atmospheric pressure is 60.34 ML approximating so this is the pressure of the gas at 0.967 on the second day.

Brainliest pls!!!

The concept Boyle's law is used here to determine the new volume of sulphur dioxide. Boyle’s law was put forward by the Anglo-Irish chemist Robert Boyle in the year 1662. Here the new volume is 60.34 mL.

A gas law known as Boyle's law asserts that a gas's pressure is inversely proportional to its volume when it is held at a fixed temperature and of a given mass. To put it another way, as long as the temperature and volume of the gas remain constant, the pressure and volume of the gas are inversely proportional to one another.

For a gas, the relationship between volume and pressure (at constant mass and temperature) can be expressed mathematically as follows.

P = k*(1/V) ⇒ PV = k

For two different gases, the equation is:

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

0.989 × 59.0 / 0.967 = 60.34 mL
