How do conduction, convection, and radiation redistribute incoming solar energy?
Answers
The climate’s heat engine must not only redistribute solar heat from the equator toward the poles, but also from the Earth’s surface and lower atmosphere back to space. Otherwise, Earth would endlessly heat up. Earth’s temperature doesn’t infinitely rise because the surface and the atmosphere are simultaneously radiating heat to space. This net flow of energy into and out of the Earth system is Earth’s energy budget. Energy from sunlight is not spread evenly over Earth. One hemisphere is always dark, receiving no solar radiation at all. On the daylight side, only the point directly under the Sun receives full-intensity solar radiation. From the equator to the poles, the Sun’ rays meet Earth at smaller and smaller angles, and the light gets spread over larger and larger surface areas (red lines). (NASA illustration by Robert Simmon.) The solar radiation received at Earth’s surface varies by time and latitude. This graph illustrates the relationship between latitude, time, and solar energy during the equinoxes. The illustrations show how the time of day (A-E) affects the angle of incoming sunlight (revealed by the length of the shadow) and the light’s intensity. On the equinoxes, the Sun rises at 6:00 a.m. everywhere. The strength of sunlight increases from sunrise until noon, when the Sun is directly overhead along the equator (casting no shadow). After noon, the strength of sunlight decreases until the Sun sets at 6:00 p.m. The tropics (from 0 to 23.5° latitude) receive about 90% of the energy compared to the equator, the mid-latitudes (45°) roughly 70%, and the Arctic and Antarctic Circles about 40%. (NASA illustration by Robert Simmon.) The amount of sunlight the Earth absorbs depends on the reflectivness of the atmosphere and the ground surface. This satellite map shows the amount of solar radiation (watts per square meter) reflected during September 2008. Along the equator, clouds reflected a large proportion of sunlight, while the pale sands of the Sahara caused the high reflectivness in North Africa. Neither pole is receiving much incoming sunlight at this time of year, so they reflect little energy even though both are ice-covered. Hope this helps!
The solar energy from sun is radiating to the earth's surface and making the atmosphere warmer. The heat energy is redistributing back by through different heat transfer modes.
What is heat transfer?Heat energy transfer from hotter region to colder region by the temperature gradient. The heat is transferring through solids by conduction. Conduction is the process of heat transfer through the closely packed particles in solids.
Heat transfers through convection in liquids. Where the hot molecules rise to the surface and transfers the heat to other molecules. The heat radiated to the earth make the sources in earth warmer. Through convection, the water molecules heat up.
The water vapor formed by convection process radiates to the atmosphere and redistributes the energy back.

Final volume of a .50 M H3PO4 solution prepared from 50 mL of a 6 M H3PO4 solution
Answers
Answer:
600 mL
Explanation:
From the question given above, the following data were obtained:
Initial concentration (C₁) = 6 M
Initial volume (V₁) = 50 mL
Final concentration (C₂) = 0.5 M
Final volume (V₂) =?
Using the dilution formula (i.e C₁V₁ = C₂V₂) we can obtain the final volume as illustrated below:
C₁V₁ = C₂V₂
6 × 50 = 0.5 × V₂
300 = 0.5 × V₂
Divide both side by 0.5
V₂ = 300 / 0.5
V₂ = 600 mL
Thus, the final volume is 600 mL

Pleaseeee!!!!
Answers
Answer:
0.862 J/gºC
Explanation:
The following data were obtained from the question:
Mass of metal (Mₘ) = 50 g
Initial temperature of metal (Tₘ) = 100 °C
Mass of water (Mᵥᵥ) = 400 g
Initial temperature of water (Tᵥᵥ) = 20 °C
Equilibrium temperature (Tₑ) = 22 °C
Specific heat capacity of water (Cᵥᵥ) = 4.2 J/gºC
Specific heat capacity of metal (Cₘ) =?
The specific heat capacity of the metal can be obtained as follow:
Heat lost by metal = MₘCₘ(Tₘ – Tₑ)
= 50 × Cₘ × (100 – 22)
= 50 × Cₘ × 78
= 3900 × Cₘ
Heat gained by water = MᵥᵥCᵥᵥ(Tₑ – Tᵥᵥ)
= 400 × 4.2 × (22 – 20)
= 400 × 4.2 × 2
= 3360 J
Heat lost by metal = Heat gained by water
3900 × Cₘ = 3360
Divide both side by 3900
Cₘ = 3360 / 3900
Cₘ = 0.862 J/gºC
Therefore, the specific heat capacity of the metal is 0.862 J/gºC

Calculate the volume, in milliliters, for the following:
.850 mol of NaNO3, from a .500 M NaNO3 solution
30.0 g of LiOH from a 2.70 M LiOH solution
Answers
Answer: The volume for 0.850 mol of [tex]NaNO_{3}[/tex] from a [tex]NaNO_{3}[/tex] solution is 1700 mL.
The volume of 30.0 g of LiOH from a 2.70 M LiOH solution is 464 mL.
Explanation:
Molarity is the number of moles of solute present in a liter of solution.
As given moles of [tex]NaNO_{3}[/tex] are 0.850 mol and molarity of [tex]NaNO_{3}[/tex] solution is 0.5 M. Hence, its volume is calculated as follows.[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\0.5 M = \frac{0.850 mol}{Volume}\\Volume = 1.7 L (1 L = 1000 mL)\\= 1700 mL[/tex]
Therefore, the volume for 0.850 mol of [tex]NaNO_{3}[/tex] from a [tex]NaNO_{3}[/tex] solution is 1700 mL.
As given mass of LiOH are 30.0 g from a 2.70 M LiOH (molar mass = 23.95 g/mol) solution. Hence, its number of moles are calculated as follows.[tex]No. of moles = \frac{mass}{molar mass}\\= \frac{30.0 g}{23.95 g/mol}\\= 1.25 mol[/tex]
So, volume for LiOH solution is calculated as follows.
[tex]Molarity = \frac{no. of moles}{Volume (in L)}\\2.70 M = \frac{1.25}{Volume}\\Volume = 0.464 L (1 L = 1000 mL)\\= 464 mL[/tex]
Therefore, volume of 30.0 g of LiOH from a 2.70 M LiOH solution is 464 mL.

Answers
Answer:
144g of H₂O
Explanation:
3NH₄ClO₄(s) + 3Al → Al₂O₃(s) + AlCl₃(s) + 3NO(g) + 6H₂O(g)
From the equation:
3 moles of NH₄ClO₄ produced 6 moles of H₂O
4 moles of NH₄ClO₄ produced ? moles of H₂O
(4 ₓ 6)/3 = [tex]\frac{24}{3}[/tex] = 8 moles of H₂O
1 mole of H₂O = (1 × 2) + 16 = 18g (The Relative Molecular mass of H₂O)
8 moles of H₂O = ?
Therefore 8 × 18 = 144g
=144g of H₂O

have a good day!Which statement about nuclear fission and nuclear fusion is not correct?
A. Both processes change atoms of one element to another element.
B. Both processes can release huge amounts of energy.
C. Both processes conserve mass.
D. Both processes produce dangerous radiation.
Answers
The statement, that describes about nuclear fission and nuclear fusion is "both processes can release huge amounts of energy."
What is nuclear fission and fusion?Nuclear fission is the process by which an atom's nucleus breaks into two or more smaller nuclei. Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process.
Fusion and fission are both nuclear reactions that yield significant amounts of energy that can be used to generate power. However, fission is the splitting of atoms, whereas fusion is the joining of them.
To put in another way, while both nuclear reactions that generate energy, the methods are vastly different. They both produce a lot of energy.
Hence the correct answer is B.

what is the difference between transmutation and natural radioactivity
Answers
During the workup portion of the reaction of alkenes with HBr as described in the experiment provided, a student transferred the reaction mixture to a separatory funnel, rinsed the reaction flask with diethyl ether, and added the ether rinses to the separatory funnel. The student then added sodium bicarbonate to the separatory funnel. Extremely vigorous bubbling occurred. What did the student do wrong
Answers
Answer:
Explanation:
Because of the acid-base reaction, as sodium bicarbonate is introduced to the separatory funnel, the additional or unreacted HBr reacts vigorously to yield CO2 gas, which exits the separatory funnel together with any dissolved compound(s) in the ether layer. This is due to a wrong and incorrect selection of the solvent mixture and the addition of sodium bicarbonate to an acidic solution.
Nothing to do with it until it has leaked out of the separatory funnel. Even then, the student may separate the components from the remaining reaction mixture by washing the ether coating layer several times with brine water, then running it into a dry sodium sulfate bed and evaporating solvent ether under decreased pressure.
