The Role of the Universal Gas Constant R in Ideal Gas Laws

Click For Summary
SUMMARY

The universal gas constant R is a fundamental proportionality constant in the ideal gas law, defined as the energy per Kelvin per mole. It relates the pressure, volume, and temperature of an ideal gas, facilitating calculations in thermodynamics. R is crucial for converting between different units and is analogous to Boltzmann's constant, but applies on a per mole basis. Understanding R is essential for accurately applying the ideal gas law in various scientific contexts.

Homework Statement



What does the R in the ideal gas constant do.

I know its a proportionality constant and it comes from a variety of equations and is related to Boltzmann, but what does it do physically?

Gets you the right answer?

It's the energy per Kelvin / mole - so similar to Boltzmann's constant but per mole
