Gases Flashcards
What are some gas laws?
- No set shape or volume
- Expands to fill containers
- Travels at different rates based on temperature
- Go through diffusion (High concentration to low concentration)
- Can be compacted by increasing the pressure
- Mix completely and spontaneously
- Constant, random movements
- Larger mass gases move slower than small mass gases
- No strong molecular forces between gases
- Low density
True or False:
Gases are the most compacted form of matter
False. Gases are the lest compacted form of matter
Do you need force to change the volume of a gas?
No
Gases have what kind of collisions?
Elastic collisions
No energy is lost
What happens with the pressure if the temperature goes up?
What kind of relationship is that?
Pressure goes up
Direct relationship
What happens with the volume if the temperature goes up?
What kind of relationship is that?
Volume goes up
Direct relationship
What happens to the pressure if the volume goes up?
What kind of relationship is that?
Pressure goes down
Indirect relationship
Why can carbon dioxide and oxygen freely diffuse?
Primary reason: The middle of the particles are hydrophobic, so they are happy to go to the lipid soluble environment
Secondary reason: Size of the particles
Why are charges not lipid soluble?
Anything with an ion is hydrophilic
What is bio-availability?
Ability for body to absorb nutrients given
What is ion-trapping?
Occurs when drug molecules change from ionized to non ionized form as it moves through compartments of the body
Explain what happens when you take aspirin and it meets your stomach
Molecules will become non ionized (lipophilic)
What happens when you take acid aspirin into an alkaline environment?
Becomes more ionized, stays hydrophilic
What happens when weakly alkaline goes into acidic?
Becomes more ionized/hydrophilic
What happens when alkaline meets with alkaline?
Becomes lipophilic/nonionized
