Question
Assuming gas molecules in a container with a movable end (a piston), which named gas law explains the resulting change due to each of following changes?
1- The effect on pressure when more gas molecules are added with the volume and temperature held constant.
2- The effect on pressure when the temperature is increased with the volume and number of molecules of gas held constant.
3- The effect on pressure when the volume is increased with the temperature and number of molecules of gas held constant.
4- The effect on volume when the number of molecules of gas is increased with the pressure and temperature held constant.
5-The effect on volume when the temperature is decreased with the pressure and number of moles of gas held constant.
CHOICES :
Charles's law.
Ideal gas law.
None of these.
Gay-Lussac's law.
Boyle's law.
Avogadro's law.
A.Charles's law.
B.Ideal gas law.
C.None of these.
D.Gay-Lussac's law.
E.Boyle's law.
F.Avogadro's law.
Explanation / Answer
(1) ========> C. Non of these.
(2) ============> D. Gay-Lussac's Law.
[Accoring to Gay-Lussac's law, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature]
(3) ============> E. Boyle's law.
[According to Boyle's Law, volume of a given mass of a gas is inversely proportional to its pressure provided the temperature remains constant]
(4)================> F. Avogadro's law
[Avogadro's Law states that the volume occupied by an ideal gas is directly proportional to the number of molecules of the gas present in the container.]
(5) ================> A. Charles Law.
[It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system]
