Answer:

Neptune planet has the coldest surface temperature.

Explanation:

  • Neptune is recognized as an Ice Monster and for a great purpose.
  • It has an ordinary temperature of nearby -215 degrees Celsius.
  • That is extremely colder than Earth's standard of 16 degrees Celsius.
  • Neptune requires a hard surface as such and rather has an icy water layer that assists as the planet's mantle.

Neptune planet has the coldest surface temperature

<u>Explanation:</u>

With temperatures falling to -218°C in Neptune’s upper atmosphere, the planet is one of the coolest in our Solar System.  Neptune is the most faraway planet from the sun. Astronomers have speculated that Neptune's huge internal temperature and the transfer of heat between the core and outer layers might be the cause why Neptune isn't significantly more chill than Uranus.

Pressures in this area range between 1 and 5 bars and the temperature reaches a high of 72 K. At this temperature, states are becoming for methane to condense, and clouds of ammonia and hydrogen sulfide are thought to form. At its core, Neptune reaches temperatures of up to 7273 K which is equivalent to the surface of the sun.

it takes 463 kJ/mol to break an oxygen-hydrogen single bond. calculate the maximum wavelength of light for which an oxygen-hydro
Marianna [84]

Answer:

  • <u>2.59 × 10⁻⁷ m  = 259 nm</u>

Explanation:

You need to calculate the wavelength of a photon with an energy equal to 463 kJ/mol, which is the energy to break an oxygen-hydrogen atom.

The energy of a photon and its wavelength are related by the Planck - Einstein equation:

  • E = hν,

Where:

  • E = energy of a photon,
  • h = Planck constant (6.626 × 10⁻³⁴ J . s) and
  • ν = frequency of the photon.

And:

  • ν = c / λ

Where:

  • c = speed of light (3.00 × 10⁸ m/s in vacuum)
  • λ = wavelength of the photon

Thus, you can derive:

  • E = h c / λ

Solve for λ:

  • λ = h c / E

Before substituting the values, convert the energy, 463 kJ/ mol, to J/bond

  • 463 kJ/ mol × 1,000 J/kJ × 1 mol / 6.022 × 10 ²³ atom × 1 bond / atom

       = 7.69×10²³ J / bond

Substitute the values and use the energy of one bond:

  • λ = 6.626 × 10⁻³⁴ J . s × 3.00 × 10⁸ m/s / 7.69×10²³ J = 2.59 × 10⁻⁷ m

The wavelength of light is usually shown in nanometers:

  • 2.59 × 10⁻⁷ m × 10⁹ nm / m = 259 nm ← answer

What is the meaning of cryosphere
nikklg [1K]

Answer:

The part of the earth’s surface where, at temperatures below 32°F (0°C), the water is frozen solid. Even a small pond while frozen over during the winter is part of the cryosphere, but cryosphere refers more often to large regions covered in snow and ice for much or all of the year, as the ice sheets of Antarctica and Greenland, glaciers, icebergs, and expanses of permafrost, all of which are especially sensitive to global shifts in climate:
