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.

When the volume of a gas is changed from 3.6 L to 15.5 L, the temperature will change from ______ C to 87 C.
harkovskaia [24]
V1/T1=V2/T2
(15.5)/(360K)=(3.6)/(T2)
T2=83.61290K

2.2 liters at 20 degrees Celsius if the pressure doesn’t change what is the new temperature at 2.6 liters
Mamont248 [21]
Based on the question, it is evident that this question rests on the premise of Charle's Law, which essentially states that temperature is proportional to volume once pressure and mass remain constant.

Thus by Charle's Equation:   \frac{ V_{1} }{ T_{1} }  =  \frac{ V_{2} }{ T_{2} }

Since the initial volume = 2.2 L; the initial temperature = 20 C; and the final volume = 2.6 L,
                           then V₁ = 2.2 L; T₁ = 20 C; V₂ = 2.6 L and what we would be
                           finding is T₂ (the final/new temperature)

Now,   T_{2}  =  \frac{(V_{2})   (T_{1}) }{V_{1}} 

     ⇒   T_{2}  =  \frac{(2.6 L)   (20  ^{o} C) }{2.2 L}

     ⇒   T_{2} = 23.64   ^{o}C


        ∴  the new temperature is ≈  23.6 °C

A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density ?
wariber [46]

Answer:

<h2>2.7 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{40.5}{15}  = 2.7 \\

We have the final answer as

<h3>2.7 g/mL</h3>

Hope this helps you

What is the difference between a molecular formula and a molecular modle?
ankoles [38]
The molecular formula tell us what elements the atoms are, and how many moles and atoms are attributed toward each element.
The molecular model tells us how the atoms/elements are bonded together.

Molecular formula : CH4

                                  H
                                   l
Molecular model:   H -- C -- H
