Gas Laws Flashcards
What are the two components of Boyles Law?
Boyles law refers to pressure and volume
What two components make up Charles Law?
Charles Law focuses on the relationship of temperature and volume. As you increase temperature, volume of a gas will expand.
What are the components focused on by Daltons law
Daltons law states that the total pressure is the sum of the pressures each individual gas. Sum=o2,nitrogen, co2, other.
What is the general principle of Grahams law?
Lighter gas diffuses (spreads out) faster than a heavier gas
Describe the general principle of henrys law
More pressure=more diffusion
-henrys law states that more pressure you apply to a gas, the more of it will be dissolved into the liquid.
Hypoxia happens at altitude due to decrease in pressure gradient.
What are the components of gay-Lussacs Law?
Temperature and pressure.
As temperature increases, so does pressure. Vv
Briefily describe the three components of ficks law of diffusion
Concentration gradient, surface area or membrane, and membrane thickness.
As altitude increases, pressure decreases creating less of a pressure gradient resulting in decreased gas-exchange.
Define the universal gas law.
The universal gas law tells us the predicted behaviour of a gas based on certain changes to certain factors. Factors include P=pressure, V=space occupied by the gas, T=average kinetic energy of gas molecules, N=amount of gas.
PV=nRT
Describe the effect of boyles law in flight
As altitude rises, pressure decreases, resulting in increased volume. Risks: Pneumothorax,etc.
Describe charles law in relation to flight.
Relates to volume and temperature.
As air heats up, volume of it will increase allowing the molecules to spread out and make air less dense, this results in weight restrictions for flight, (less lift)
How does Daltons law pertain to flight ops?
Increasing altitude results in a proprtional decrease in the partial pressures of the gases found in the atmosphere. Applies to ABG analysis in flight, hypoxia sec. Decreased po2. In addition, the partial pressures of each gas will decrease resulting in less lift for the aircraft
How does flight affect ficks law?
The rate of diffusion is affected by atmospheric pressure, surface area and membrane thickness. Flight enviornment has less atmospheric pressure impairing rate of diffusion
Explain the universal gas-law concept
PV=nRT
The universal gas law equation unifies the relationship between pressure, volume, temperature.
As altitude rises, pressure will decrease and so will temperature, resulting in volume increasing, risks of pneuothorax, free gas expansion within the body, gastric, ICP etc.
Explain Boyles law easily
Pressure and volume have an inverse relationship.
Explain charles law easily
When you heat up a gas, it expands an takes up more room (V/T)
