Intro To Gases Flashcards
What are the three phases of matter?
solid
liquid
gas
Compare solid, liquid, gas in terms of shape, volume, and particle movement
Solid: definite shape and volume
Liquid: definite volume, takes shape of contaimer
Gas: takes shape and volume of container; fast particle movement
particle movement increases going from solid -> liquid -> gas
What are the 4 variables of gas?
- Pressure (P)
- Volume (V)
- Temperature (T)
- Amount of gas (n)
Know the relationship between different pressure units. Ex: 1 atm = ?
1 atm =
- 760 mmHg
- 760 torr
- 1.01325 x 10⁵ Pa
- (29.92 Hg)
- (14.7 psi)
Know the relationship between different pressure units. Ex: 1 kPa = ?
1000 Pa
What is the formula for converting from Celcius to Farenheight
F = 1.8 (C) + 32
What is the formula for converting from Farenheight to Celcius
C = F - 32 / 1.8
( i think lol )
What is the formula for converting from Celcius to Kelvin
K = C + 273
What is the formula for converting from Kelvin to Celcius
C = K - 273
What order would you need to convert to find Farenheight given Kelvin
K -> C -> F
T/F: The volume of gas is NOT equal to the size of the container in which the gas is placed in
False, the volume of gas IS equal to the size of the container that gas is in, because gas takes the volume and shape of a container its in.
1mL = ? cc (cm³)
1 cc (cm³)
When solving equations, according to gas law, the units used for temperature should always be in ______
Kelvin
What is the relationship between temperature and molecule movement?
↑temp = ↑molecule mvt/speed
↓temp = ↓molecule mvt/speed
“Amount” is a property of gas, which measures the quantity of gas present in a container. The units for these are _______ or _______
grams (g) or moles (m)
Who is the father of modern chemistry?
Robert Boyle
What is Boyles law? What are the two variables involved and how do they relate to one another?
Boyles law: Pressure and volume are inversely related at a constant temperature
↑Pressure = ↓Volume
↓Pressure = ↑Volume
What is the equation used for Boyles law?
P₁V₁ = P₂V₂
What is Charles law? What are the two variables involved and how do they relate to one another?
Charles law: volume of gas varies directly with the absolute temperature at a constant pressure
↑Volume = ↑Temperature
↓Volume = ↓Temperature
What is the equation for Charles Law?
V₁/T₁ = V₂/T₂
Define: Aura
eruption of gasses by the sun
What is Gay-Lussac’s law? What are the two variables involved and how do they relate to one another?
Gay-Lussac Law: Pressure and absolute temperature are directly related at a constant volume
↑Pressure = ↑Temperature
↓Pressure = ↓Temperature
What is the equation for Gay Lussac’s Law?
P₁/T₁ = P₂/T₂
What is Avogadros’s law? What are the two variables involved and how do they relate to one another?
Avogadros Law: The volume of gas is directly related to the number of moles at a constant temperature and pressure
What is the formula for avogadros law?
V₁/n₁ = V₂/n₂
What is Daltons’s law?
total pressure is the sum of the partial pressures
What is the formula for the combined gas law?
P₁V₁/T₁ = P₂V₂/T₂
What does STP stand for?
Standard Temperature and Pressure
At STP,
- Temperature = ?
- Pressure =?
- Volume of 1 mol gas =
Temperature = O°C (273K)
Pressure = 1 atm (760mmHg)
Vol 1 mol gas = 22.4L
