Thomas Graham
________, a Scottish scientist, discovered in 1832 that rates of diffusion for gases are inversely proportional to the square roots of their molar weights under the same conditions of temperature and pressure.
New cards
3
gaseous state
The gas laws and kinetic molecular theory assume that molecules in the ________ have no attraction or repulsive force on one another.
New cards
4
manometer
A(n) ________ is a device that is used to determine the pressure of gases other than air.
New cards
5
Density
________ is represented as n /V because the mass of the gas is directly proportional to the number of moles (n) in the gas.
New cards
6
Dalton
________ established the law of partial pressures in 1801, which states that the total pressure of a mixture of gases is equal to the sum of the pressures that each gas would exert if it were present alone.

7
Kelvin
One ________ (K) is the same as one degree Celsius on the ________ scale.
New cards
8
proportionality constant
The ________, R, is referred to as the gas constant.
New cards
9
absolute temperature
The volume of a fixed amount of gas maintained at constant pressure is exactly proportional to the ________ of the gas, according to Charles 'law.
New cards
10
Absolute zero
________, or 273.15°C, is the lowest temperature that may theoretically be reached.

Diffusion
________ is the process of a gas progressively mixing with another, while effusion is the process of a gas under pressure escaping from one compartment of a container to another through a small opening.
