1. air components change from place to place, while water will just stay the same
2. Water doesn't have nor show individual properties, but air does show that it has it's own property
3. You can separate different gases from air physically, but with water you must pass electricity through it.
Don't take my word for it, this is just what I learned back in middle school.
Answer:
The final pressure is 2.25 atm or 1710 mm Hg
Explanation:
Step 1: Data given
The initial volume = 28.4 L
The initial pressure = 725 mm Hg ( = 725/760 atm) = 0.953947 atm
The initial temperature = 305 K
The new volume is 14.8 L
The new temperature = 375 K
Step 2: Calculate the new pressure
(P1*V1)/T1 = (P2*V2)/T2
⇒ with P1 = the initial pressure = 725 mmHg = 0.953947 atm
⇒ with V1 = the initial volume = 28.4 L
⇒ with T1 = The initial temperature = 305 K
⇒ with P2 = the new pressure = TO BE DETERMINED
⇒ with V2 = the new volume = 14.8 L
⇒ with T2 = the new temperature = 375 K
(0.953947 * 28.4)/305 = (P2 * 14.8)/375
P2 = 2.25 atm = 1710 mm Hg
The final pressure is 2.25 atm or 1710 mm Hg

Answer:
When white glue is in the bottle, there's not enough air inside the bottle to cause the water to evaporate to make the glue sticky. Basically, the bottle holds the glue from the air and keeps the glue from going everywhere.
Answer:
A) involves changes in temperature
Explanation:
The figure is missing, but I assume that the region marked X represents the region in common between Gay-Lussac's law and Charle's Law.
Gay-Lussac's law states that:
"For an ideal gas kept at constant volume, the pressure of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where p is the pressure of the gas and T its absolute temperature.
Charle's Law states that:
"For an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically, it can be written as
where V is the volume of the gas and T its absolute temperature.
By looking at the two descriptions of the law, we see immediately that the property that they have in common is
A) involves changes in temperature
Since the temperature is NOT kept constant in the two laws.
