This type of radiation is smallest and highest in energy

1 answer:

5 0

As your question is vague, I am assuming that you are talking Alpha, Beta and Gamma radiation. Out of these three radiation, Gamma radiation is the smallest in size compared to Alpha or Beta, but it has the highest energy levels. Gamma radiation is also known as photons. In other words, photons are light particles.

Which statement correctly compares the thicknesses of Earth’s layers? Earth’s mantle is thinner than its oceanic crust. Earth’s

Harman [31]

“The Earth’s lithosphere is thinner than its asthenosphere”, the statement correctly compares the thicknesses of Earth’s layers

Answer: Option D

<u>Explanation: </u>

The outermost parts of the Earth composed of crust and a part of the upper mantle is termed as lithosphere. And asthenosphere is positioned below lithosphere. The bottom layer of lithosphere has the parts of the upper crust.

So the highly viscous and ductile region in the remaining part of the upper crust forms the asthenosphere below the lithosphere. The upper crust in the lithosphere region contain elastic properties while the upper crust in the asthenosphere is ductile in nature. Thus the statement that lithosphere is thinner than asthenosphere is true as it is located at the surface.

Sodium sulfide reacts with hydrochloric acid to produce hydrosulfuric acid and sodium chloride. (you need to write and balance t

VikaD [51]

Answer:

2.5 moles of NaCl

Explanation:

The balanced chemical reaction equation is shown in the image. Since it takes 2 moles of Hydrochloric acid to form two moles of sodium. Chloride, then 2.5 moles of hydrochloric acid should also form 2.5 moles of sodium chloride according to the balanced reaction equation.

One kilogram of water at 100 0C is cooled reversibly to 15 0C. Compute the change in entropy. Specific heat of water is 4190 J/K

mina [271]

Answer:

The change in entropy is -1083.112 joules per kilogram-Kelvin.

Explanation:

If the water is cooled reversibly with no phase changes, then there is no entropy generation during the entire process. By the Second Law of Thermodynamics, we represent the change of entropy ( $s_{2} - s_{1}$ ), in joules per gram-Kelvin, by the following model:

$s_{2} - s_{1} = \int\limits^{T_{2}}_{T_{1}} {\frac{dQ}{T} }$

$s_{2} - s_{1} = m\cdot c_{w} \cdot \int\limits^{T_{2}}_{T_{1}} {\frac{dT}{T} }$

$s_{2} - s_{1} = m\cdot c_{w} \cdot \ln \frac{T_{2}}{T_{1}}$ (1)

Where:

$m$ - Mass, in kilograms.

$c_{w}$ - Specific heat of water, in joules per kilogram-Kelvin.

$T_{1}$ , $T_{2}$ - Initial and final temperatures of water, in Kelvin.

If we know that $m = 1\,kg$ , $c_{w} = 4190\,\frac{J}{kg\cdot K}$ , $T_{1} = 373.15\,K$ and $T_{2} = 288.15\,K$ , then the change in entropy for the entire process is:

$s_{2} - s_{1} = (1\,kg) \cdot \left(4190\,\frac{J}{kg\cdot K} \right)\cdot \ln \frac{288.15\,K}{373.15\,K}$

$s_{2} - s_{1} = -1083.112\,\frac{J}{kg\cdot K}$

The change in entropy is -1083.112 joules per kilogram-Kelvin.

What would be another property that we Earthlings could use to classify stars?

Blizzard [7]

Answer: At the point when space experts take a gander at an article's range, they can decide its arrangement dependent on these frequencies. The most well-known technique stargazers use to decide the sythesis of stars, planets, and different articles is spectroscopy. This spread-out light is known as a range.
