<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.
Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust
<h2>Hello!</h2>
The answer is: -97.37° C
<h2>Why?</h2>
According to the Charles and Gay-Lussac's Law we have that:

Where:
<em>v</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
From the Gay-Lussac's Law we also have the following relation:

Since we need to find the new temperature (T2) we can use the last equation:

We are asked to find the temperature in Celsius degrees, so, we must convert the result (in K) to Celsius degrees:

So, the temperature is -97.37° C
Have a nice day!
Answer: the mass number of an element is equal to the number of protons plus the number of neutrons.
Answer:
Density = 8.75ml
Explanation:
Density = Mass / Volume
In this problem ...
Mass = 28 grams
Volume = 31.4ml - 28.2ml = 32ml (water displacement also)
∴Density = mass /volume = 28g/32ml = 8.75g/ml
