The angle of insolation has the effect that the more the angle of insolation, the more the amount of heat absorbed by a material.
The impact of the insolation angle on the heat absorption rate of a substance can be explained by the following factors that affect how much sunlight is absorbed on Earth's surface:
The soil will be warmer because it will catch more direct light if somehow the angle of insolation is higher.The sun's rays' insolation angle is the angle at which the rays strike a specific spot on Earth.The elevation of the sun in the sky in reference to the observer is referred to as the angle of insolation. Angles of insolation start at 0 degrees.The Earth orbits the sun in an elliptical route rather than a perfect circle, thus some seasons of the year see Earth closer to the sun than others.The angle of insolation of the earth's axis: The earth's axis is inclined by 66 [tex]\frac{1}{2}[/tex] degrees with respect to its orbital plane.Read more about the Angle of insolation from:

Incorporate the meaning distance and displacement in the poem tagalog or English not necessarily the exact definition halimbawa: Itong mga dayuhan bago nakarating sa ating Bayan ay naglakbay ng ilang milya mula kanluran papuntang timog silangan
Answer:
Displacement.
Explanation:
The example i.e. these foreigners before arriving in our Town traveled several miles from west to southeast represents displacement not distance because in this example direction of the objects are given. We know that distance is a scalar quantity which is expressed from its magnitude only while on the other hand, displacement is a vector quantity which can be fully explained through magnitude as well as direction of the object. in this example, west to southeast represents direction of the objects so we can say that it refers to the displacement.

Si Hecho Dos Cubos de Hielo En Un Vaso Con Agua Señalo Donde Quedo El Nivel Del Agua, Luego A Pasar El Tiempo Dejo Que Se Derritan Los Cubos De Hielo El Nivel Del Agua Aumenta??
Answer:
Ver explicacion
Explanation:
Técnicamente, cuando el hielo se derrite, ocupa aproximadamente el mismo volumen de agua que es igual a la masa de agua desplazada antes de que el hielo se derrita. Esto es posible solo cuando se ignora el cambio en la densidad del agua.
Sin embargo, si tenemos en cuenta el ligero cambio en la densidad del agua, se puede demostrar que el volumen de hielo es mayor que el del agua líquida porque el agua se expande cuando se congela.
Esto significa que el volumen de agua disminuye cuando el hielo se derrite.
how many moles of sodium phosphate are required to make 7.5 moles of sodium nitrate in 2Na3PO4+3Be(NO3)=6NanO3+Be3(PO4)2

What is a compound?
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

PH3(g)1/4 P4(g) + 3/2 H2(g)
is first order in PH3 with a rate constant of 1.80×10-2 s-1.
If the initial concentration of PH3 is 8.48×10-2 M, the concentration of PH3 will be 2.45×10-2 M after
s have passed.
Answer:
The decreasing in concentration occurs after 69.0s
Explanation:
A first order reaction follows the equation:
Ln [A] = -kt + ln[A]₀
Where [A] is the concentration of the reactant after time t
k is rate constant of the reaction
And [A]₀ is the initial concentration of the reactant
Replacing:
Ln 2.45x10⁻²M = -1.80x10⁻²s⁻¹*t + ln8.48x10⁻²
-3.709 = -1.80x10⁻²s⁻¹*t -2.467
-1.2416 = -1.80x10⁻²s⁻¹*t
69.0s = t
The decreasing in concentration occurs after 69.0s

How does the rate of a chemical reaction change if the concentration of both reactants increases 4 times?
2NO + O2 → 2 NO2
Answer: The rate will increase 32 times if the concentration of both reactants increases 4 times
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For the reaction : [tex]2NO+O_2\rightarrow 2NO_2[/tex] [tex]rate=k[NO]^2[O_2]^1[/tex]
k= rate constant
order with respect to [tex]NO_2[/tex] = 2
order with respect to [tex]O_2[/tex] = 1
Thus on increasing the concentration of reactants 4 times :
[tex]rate'=k[4\times NO]^2[4\times O_2]^1[/tex]
[tex]rate'=k\times 8\times 4\times [NO]^2\times [O_2]^1[/tex]
[tex]rate'=32\times rate[/tex]
Thus rate will increase 32 times if the concentration of both reactants increases 4 times
A student weighs an empty flask and stopper and finds the mass to be 53.256 g. She then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 98.8°C. After all the liquid is vaporized, she removes the flask from the bath, stoppers it, and lets it cool. After it is cool, she momen- tarily removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 53.780 g. The volume of the flask is known to be 231.1 mL. The absolute atmospheric pressure in the laboratory that day is 728 mm Hg. a. What was the pressure of the vapor in the flask in atm?
Answer:
a. The pressure in the flask open to the atmosphere during the vaporization of the unknown liquid is equal to the prevailing atmospheric pressure equivalent to 0.957734 atm
Explanation:
The mass of the empty flask and stopper, m = 53.256 g
The volume of the unknown liquid she adds = 5 mL
The temperature of the water in which she heats up the flask = 98.8 °C = 371.95 K
The mass of the flask and the condensed vapor = 53.780 g
The volume of the flask, V = 231.1 mL
The atmospheric pressure, P = 728 mm Hg
a. We note that the student stoppers the flask after all the liquid has evaporated. Therefore, given that the flask was open to the atmospheric pressure as the liquid evaporates, the pressure of the vapor in the flask is equal to the prevailing atmospheric pressure, or 728 mmHg
Using a calculator, 728 mm Hg is equivalent to 0.957734 atm.
