At temperature, a sample of neon gas will occupy
volume.
Further Explanation:
The given problem is based on the concept of Charles’ law. Charles’ law states that “at constant pressure and fixed mass the volume occupied an ideal gas is directly proportional to the Kelvin temperature.”
Mathematically the law can be expressed as,
Or,
Here, <em>V</em> is the volume of the gas, <em>T</em> is Kelvin temperature, and <em>k</em> is proportionality constant.
Given information:
The initial volume of neon gas is .
The final volume of neon gas is .
The initial temperature value is .
To calculate:
The final temperature
Given Condition:
- The pressure is constant.
- Mass of gas is fixed.
Solution:
Step 1: Modify the mathematical expression for Charles’ law for two different temperature and volume values as follows:
Here,
is the initial volume of the gas.
is the final volume of the gas.
is the initial temperature of the gas.
is the final temperature of the gas.
Step 2: Rearrange equation (2) for .
…… (2)
Step 3: Convert the given temperature from degree Celsius to Kelvin.
The conversion factor to convert degree Celsius to Kelvin is,
…… (3)
Substitute for
in equation (3) to convert temperature from degree Celsius to Kelvin.
Step 4: Substitute for
,
for
and
for
in equation (2) and calculate the value of
.
Important note:
- The temperature must be in Kelvin.
- The condition of fixed mass and fixed pressure must be fulfilled in order to apply Charles’ law.

Answer : The oxidation number of chlorine (Cl) is, (+1)
Explanation :
Oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
Rules for Oxidation Numbers :
The oxidation number of a free element is always zero.
The oxidation number of a monatomic ion equals the charge of the ion.
The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
The given compound is,
Let the oxidation state of 'Cl' be, 'x'
Therefore, the oxidation number of chlorine (Cl) is, (+1)
