Random Gas Stuff
At STP, for every 1 mole of gas, you have...
22.4 L
What does STP stand for, and what conditions does STP give?
standard temperature and pressure, which is 0 degrees Celsius and 1 atm
What is Charles' Law?
V1/T1 = V2/T2
What is the equation for the combined gas law?
P1V1/T1 = P2V2/T2
How many different 'R' constants are there?
3
What are two characteristic properties of gases?
Small Spherical Particles
Highly Compressible
What kind of relationship exists between Pressure and Temperature?
A direct Relationship
When one increases, the other increases
What are the three different units for Pressure?
atmospheres (atm)
kilopascals (kPa)
millimeters of mercury (mmHg)
In the ideal gas law equation, which the 'n' variable stands for...
moles
A volume of air occupying 2.00L at 2 atm is compressed to a pressure of 4 atm. The temperature remains constant. What is the new volume?
The volume would be 1.00 L
The Combined Gas Law is an amalgamation of which three laws?
Boyle's Law, Charles' Law, and Gay-Lussac's Law
Why do were have 3 different molar constant (R) values?
The molar constants relate moles to pressure, and we have 3 different pressure units.
What does Avogadro's law state?
Equal volumes of any two gases at the same temperature and pressure contain the same number of molecules.
Which law most relates to the Oceangate incident, and why?
Boyle's Law (P1V1 = P2V2)
The submarine gained pressure, which caused its' volume to shrink.
A helium-filled weather balloon has a volume of 100 L at 200 Kelvin and 1 atm. It is released and rises to an altitude of 2.63 km, where the pressure is 0.5 atm and the temperature is 100 Kelvin. What is the volume at these new conditions?
It would be the same, 100 L
Kinetic Molecular Theory states:
Gases are composed of numerous small, spherical particles in constant, random motion, bouncing off each other and their surroundings in perfectly elastic collisions, and can be compressed or expand.
