Interpretation:
The temperature of the gas is to be calculated in
Concept introduction:
When volume and amount of gas are kept constant, increasing the temperature of gas increases its pressure. This law is known as Gay Lussac’s Law.
According to this law,
Where
Answer to Problem 9PP
The initial temperature of the gas is
Explanation of Solution
Given information:
The initial pressure
The final temperature is
The final pressure is
The change in pressure on changing the temperature of the gas keeping the volume and amount of gas fixed is studied by a law named as Gay Lussac’s Law. According to this law, the pressure of a given mass of gas is directly proportional to the Kelvin temperature at constant volume.
If
Or
Where
As temperature is given in degree Celsius, so firstly convert it into Kelvin.
Therefore
On substituting the values in the formula:
If result is to be reported in
Therefore
Therefore, initial temperature is
The temperature of the gas is
