Answer:
The false statement is: (C) The average kinetic energy of the molecules is not related to the absolute temperature
Explanation:
According to the Kinetic Theory of Gases, gases are composed of <u>small fast moving particles that are in constant random motion</u>. These gaseous particles are known as molecules.
It is assumed that the mass of all the gaseous molecules is the same and the <u><em>intermolecular interactions (attractive or repulsive) are negligible</em></u>.
Also, the <em><u>total volume of all the gaseous molecules is considered to be negligible as compared to the volume of the container.</u></em>
According to this theory, <em><u>average kinetic energy (K) of the gaseous particles is directly proportional to the absolute temperature (T) of the gas, </u></em>by the equation:

<em>Here, </em>
<em> is the Boltzmann constant</em>
<u>Therefore, the false statement about the kinetic molecular theory is (C)</u>
Answer:
The answer to your question is V2 = 5.09 l
Explanation:
Data
Volume 1 = V1 = 5.0 L
Temperature 1 = T1 = 5°C
Volume 2 = V2 = ?
Temperature 2 = T2 = 10°C
Formula (Charles law)
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Convert temperature to °K
T1 = 5 + 273 = 278°K
T2 = 10 + 273 = 283°K
-Substitution
V2 = (5)(283) / (278)
-Simplification
V2 = 1415 / 278
-Result
V2 = 5.09 l
Answer:
58.3%
Explanation:
The formula of the compound is given as:
CsPO₄
Now, the percentage composition of Cs in the compound is = ?
So;
To find this parameter, find the molar mass of the compound:
Molar mass of CsPO₄ = 132.9 + 31 + 4(16) = 227.9g/mol
Percentage composition of Cs=
= 58.3%
