Sample Response: <em>The process that lead to this difference in fur color is called "natural selection." Polar Bears live in the arctic, where there is snow all around. In this kind of environment, white bears blend in well with their surroundings while brown and black bears stand out. This means that brown and black bears would be easier to spot as prey, and would not survive in an arctic environment. Since white bears are more adapted to the environment, they would survive and reproduce, creating a large population of white bears.</em>

This is called adaptation. An example would be a polar bear with white fur. They have this to be more efficent hunters, as they use it as a type of camouflage in order to sneak up on prey. Brown bear use this in the same way but their environment requires them to be brown in order to blend in beter with trees. So basicly adaptation

<u>The answer is B. Gas molecules are in Constant Motion.</u>

This is supported by the Kinetic Theory of Gases, which it states that the gas particles are in constant random motion, colliding with the container that it's in.

How many liters would 4.56 mol sulfur dioxide occupy at STP?
algol13

The volume of Sulfur dioxide-SO₂ at STP : = 102.144 L

<h3>Further explanation</h3>

Given

4.56 mol Sulfur dioxide-SO₂

Required

The volume

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

so for 4.56 mol :

= 4.56 x 22.4 L

= 102.144 L

When the temperature of a sample of neon gas increases, what else increases? Distance between the atoms Kinetic energy of the at
Allushta [10]

Answer: Kinetic Energy of the atoms also increases.

Explanation: We are given that the temperature of the gas increases.

Relation between kinetic energy and temperature follows:

K.E._({avg})=\frac{3RT}{2N_A}

where, K = Average Kinetic energy

R = Gas constant

T = Temperature

N_A = Avogadro's number

As seen from the relation above, the Kinetic energy of the gas is directly proportional to the temperature, hence as the temperature increases, kinetic energy of the atom also increases.
