Equations
How do you find density?
d=M/V
What is Density?
Degree of compactness of a substance
What is density measured in?
Either kg/m cubed or g/cm cubed
What is the relationship between density and mass?
Their Directly proportional
What do Scientists believe greenhouse gasses will do?
lower the density in the atmosphere
What is the Ideal Gas Law
PV = nRT
What does Ideal Gas Law state?
It states the product of pressure, volume of gas, and temperature are related
PV=nRT; state what does each letter stand for and there unit of measurement?
P=Pressure atm
V=Volume L
n=number of moles of gas
R=Ideal Gas constant
T=Absolute Temperature
What is the relationship between volume and pressure?
Indirectly Proportional
How does Ideal Gas Law relate to climate change?
Increasing air temperature increases volume of air so the air density decreases as temperature increases
What is the Combined Gas Law?
P1V1/T1 = P2V2/T2
What is the Combined Gas Law Definition?
It states the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant
PV/T=K; state what does each letter stand for?
P=Pressure atm
V=Volume L
T=Temp. In Kelvin (0 K=-273.15)
K=Temperature Constant
What relationship is expressed in combined gas law?
The relationship between the pressure of volume and the pressure of fixed amount of gas
What is combined Gas Law responsible for in our environment
Combined Gas Law is responsible for helping predict things such as cloud formation because it applies whenever gas remains constant but pressure, volume, and temp. change
1 mole is equal to how many particles?
6.02x10^23 particles/atoms
What is a mole?
A unit that represents how many particles (atoms) are in something
What is the unit for density if the substance is solid?
Grams per cubic centimeter OR
g/cm^3
What is the relationship between moles and density?
Molar Mass is equal to density multiplied by Molar Volume
How do moles affect greenhouse gasses?
Gasses get trapped in Earth's outgoing energy, therefore heating up the earth because the heat cant escape the atmosphere
