A student uses 0.0821 L• atm/mol • K as the value of the gas constant. What is most likely true about the variables in the ideal gas law?




P has the units of liters • atmospheres, and T has the units of kelvin.


P has the units of liters • atmospheres, and T has the units of degrees Celsius.


V has the units of liters, and T has the units of kelvin.


V has the units of liters, and T has the units of degrees Celsius.

Considering P represents pressure why god would it be measured in liters. Ignore the first 2 choices.
With all gas law related questions you never use Celsius temperatures.
The answer has to be V has units of liters, and T has the units of kelvin.

Answer is: V has the units of liters, and T has the units of kelvin.

Ideal gas law: p·V = n·R·T.  

atm · L = mol · L·atm/mol·K · K; both side of equatation have same values.

R = 0,08206 L·atm/mol·K; universal gas constant.  

p is pressure of the gas, unit is standard atmosphere (atm).

V is volume of the gas, unit is liters (L).

n is amount of substance of the gas; unit is mole (mol).

T is temperature of the gas, unit is Kelvin (K).
