Interpretation:
The apparatus has to be redrawn if the temperature is increased from
Concept introduction:
Charles’s law: States that volume is directly proportional to temperature when the gas is held at constant pressure and number of molecules.
(a)

Answer to Problem 8.26UKC
According to Charles’s law, if temperature increases at constant pressure, then volume also increases. Therefore, the apparatus is redrawn as given below:
Explanation of Solution
Given data is that the temperature increases from
Charles’s law is the
From Charles’s law we know that
According to Charles’s law, if temperature increases at constant pressure, then volume also increases. Therefore, the apparatus is redrawn as given below:
(b)
Interpretation:
The apparatus has to be redrawn if the pressure is increased from
Concept introduction:
Boyle’s law:
At fixed temperature, the volume of a fixed amount of gas is inversely proportional to the pressure exerted by the gas.
(b)

Answer to Problem 8.26UKC
According to Boyle’s law, if pressure increases at constant temperature, then volume decreases. Therefore, the apparatus is redrawn as given below:
Explanation of Solution
Given data is that the pressure is increased from
Boyle’s law is the law which relates pressure and volume at a constant temperature and number of molecules.
From Boyle’s law:
According to Boyle’s law, if pressure increases at constant temperature, then volume decreases. Therefore, the apparatus is redrawn as given below:
(c)
Interpretation:
The apparatus has to be redrawn if the temperature is decreased from
Concept introduction:
General Gas Law:
Combining Charles’s law and Boyle’s law we get the General gas law or combined gas law.
(c)

Answer to Problem 8.26UKC
The volume remains unchanged and the apparatus is redrawn as given below:
Explanation of Solution
Given data is that the temperature is decreased from
Combined gas law is proposed by combining the Boyle’s law and Charle’s law and is given by:
Therefore, the volume remains unchanged and the apparatus is redrawn as given below:
