Use this image of a greenhouse to help explain how the Earth gets heated through the greenhouse effect.
Answers
Answer/Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 58 degrees Fahrenheit (14 degrees Celsius), on average.

an amount of 54.11 grams of pentane, c5h12 ,is equal to
Answers
First you need to find the molar mass of pentane.
Molar mass of C is 12.01 and molar mass of H is 1.008.
12.01*5 +1.007*12 = 60.05 + 12.08 = 72.13 grams C5H12 per mole
54.11/72.13 = 0.75 moles C5H12
So your answer is 0.75 moles C5H12

The weight of the elephant is 4500 kg, and the area of the sole of one of its legs is 1700 cm2. Calculate the pressure of the elephant on the ground.
Answers
Answer:
64852.94 N/m²
Explanation:
From the question,
P = F/A.................... Equation 1
Where P = Pressure of the Elephant on the ground, F = Weight of the Elephant, A = Area of the sole of the four legs.
But,
F = mg.............. Equation 2
Where m = mass of the elephant, g = acceleration due to gravity
Substitute equation 2 into equation 1
P = mg/A............ Equation 3
Given: m = 4500 kg, A = (1700×4) cm² ( The elephant has four legs) = 6800 cm² = 0.68 m²
Constant; g = 9.8 m/s²
Substitute these values into equation 3
P = (4500×9.8)/0.68
P = 64852.94 N/m²

Explanation:
You place air in a sealed can at standard temperature and pressure (STP). You double its absolute temperature (K) while leaving the
volume constant.
What happens to the pressure?
It doubles.
It decreases by one-half.
It increases to four times the original pressure.
It stays the same.
Answers
Answer:
Pressure will double
Explanation:
Gay - Lussac Law => P ∝ T with volume and mass held constant.
=> P₁/T₁ = P₂/T₂ => P₂ = P₁T₂/T₁
T₂ = 2T₁
P₂ = P₁(2T₁)/T₁ = 2P₁
Double absolute temperature => double pressure

For a given substance, the molar heat of fusion basically tells you one thing from two perspectives
how much heat is needed in order to melt one mole of that substance at its melting point
how much heat must be removed in order to freeze one mole of that substance at its freezing point
It is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.

Qué es Crecimiento poblacional:
El crecimiento poblacional se refiere al incremento del número de habitantes en un espacio y tiempo determinado, el cual se puede medir a través de una fórmula aritmética. También se puede emplear como sinónimo el término crecimiento demográfico.
Cuando se hace mención al crecimiento poblacional se puede hacer referencia a cualquier especie animal, sin embargo, se suele usar para referirse a los seres humanos, en especial cuando se realizan investigaciones acerca del crecimiento de la población.
Los datos que se obtienen de estos análisis son de gran importancia, tanto para los gobiernos de un país como, para las diferentes organizaciones internacionales.
Cabe resaltar que durante el siglo XX la población de seres humanos ha crecido y sigue creciendo en gran porcentaje, lo que ha generado preocupación, en especial por sus consecuencias sobre el uso y cuidado de los recursos naturales, entre otros.
Las zonas urbanas son las que presentan mayor crecimiento demográfico, así como, los países en vías de desarrollo. Por el contrario, el crecimiento poblacional es menor en los países desarrollados.
Por ejemplo, el crecimiento poblacional en México ha ido en aumento a lo largo de su historia, es el país con más habitantes hispanohablantes en América Latina. México tiene una población aproximada a 130 millones de habitantes, y se estima que seguirá creciendo gracias a diversos factores gracias a su continuo desarrollo político, económico y social.
