The Earth experiences an ice age when the overall climate becomes much cooler. During an ice age, there are several periods of g

laciation, which are periods when glaciers and ice sheets cover more of the Earth's surface. Ice reflects more sunlight back into outer space than does bare or vegetated ground. Because ice sheets and glaciers are more reflective, they absorb less sunlight and therefore release _______ heat. This causes the Earth's climate to become _______ during periods of glaciation.

The given blank can be filled with less and even cooler.

A long duration of decline in the temperature of the surface of the Earth and atmosphere, leading to the expansion or existence of the polar and continental ice sheets and alpine glaciers is known as an ice age.  

During an ice age, there are many periods of glaciation that are periods when ice sheets and glaciers cover the majority of the Earth's surface.  

The ice reflects more sunlight back into outer space than does the vegetated or bare ground. As the glaciers and ice sheets are more reflective, they captivate less sunlight and thus discharge less heat. This makes the climate of the Earth to become even cooler during the times of glaciation.

A gas occupies the volume of 215ml at 15C and 86.4kPa?
kherson [118]

Answer:

About 0.1738 liters

Explanation:

Using the formula PV=nRT, where p represents pressure in atmospheres, v represents volume in liters, n represents the number of moles of ideal gas, R represents the ideal gas constant, and T represents the temperature in kelvin, you can solve this problem. But first, you need to convert to the proper units. 215ml=0.215L, 86.4kPa is about 0.8527 atmospheres, and 15C is 288K. Plugging this into the equation, you get:

0.8527\cdot 0.215=n \cdot 0.0821 \cdot 288\\n\approx 7.754 \cdot 10^{-3}

Now that you know the number of moles of gas, you can plug back into the equation with STP conditions:

1V=7.754 \cdot 10^{-3} \cdot 0.0821 \cdot 273\\V\approx 0.1738L

Hope this helps!

How is condensation explained by the Kinetic Molecular Theory? Cooling reduces particle motion, resulting in coalescence by attr
lara31 [8.8K]

Temperature means, in this context, movement.

Condensation can be explained by the reduction of temperature of the system. This effect make possible the cohesion forces increases. In other words, the result is coalescence by attractive forces.

How many atoms are in 13.97 liters of water vapor at STP
Arisa [49]
<span>Let's </span>assume that water vapor has ideal gas behavior. <span>
Then we can use ideal gas formula,
PV = nRT<span>

</span><span>Where, P is the pressure of the gas (Pa), V is the volume of the gas (m³), n is the number of moles of gas (mol), R is the universal gas constant ( 8.314 J mol</span></span>⁻¹ K⁻¹) and T is temperature in Kelvin.<span>
<span>
</span>P = 1 atm = 101325 Pa (standard pressure)
V = 13.97 L = 13.97 x 10</span>⁻³ m³<span>
n = ?
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
T = 0 °C = 273 K (standard temperature)
<span>
By substitution,
</span>101325 Pa x 13.97x 10</span>⁻³ m³ = n x 8.314 J mol⁻¹ K⁻¹ x 273 K<span>
                                          n = 0.624 mol
<span>
Hence, the moles of water vapor at STP is 0.624 mol.

According to the </span></span>Avogadro's constant, 1 mole of substance has 6.022 × 10²³ particles.
<span>
Hence, number of atoms in water vapor = 0.624 mol x </span>6.022 × 10²³ mol⁻¹
<span>                                                                = 3.758 x 10</span>²³<span>

How does the geosphere and biosphere interact
Vlada [557]

The geosphere, in turn, reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere.

Explanation:

  • The geosphere, in return reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight energy from the atmosphere.
  • Scientists divide the planet into two the main components: the biosphere, which consists of all life.
  • The hydrosphere interacts with the geosphere when particles of water or rain cause land formations to erode.
  • biosphere is the part of the earth and its atmosphere capable of supporting life.
  • Geo sphere is the solid body of the earth.
  • Biosphere is the totality of living organisms and their environment.
