Question

What do each of the following measure and what are the units for each of the variables listed?
Temperature: measures kinetic energy; Kelvin (K)
Pressure:
Volume:
N:
R: Gas Constant: 0.0821L•atmmol•K

Answer 1

Certainly! Below are the measurements and units for each of the gas law variables you listed:

1. Temperature:

   • Measures: Kinetic energy of gas molecules.
   • Units: Kelvin (K).

2. Pressure:

   • Measures: The force exerted by gas molecules colliding with the walls of their container.
   • Units: Common units include:
     • Atmosphere (atm)
     • Pascals (Pa)
     • Millimeters of mercury (mmHg)
     • Torr
     • Pounds per square inch (psi)

3. Volume:

   • Measures: The space occupied by the gas.
   • Units: Common units include:
     • Liters (L)
     • Milliliters (mL)
     • Cubic meters (m³)

4. N (Moles of gas):

   • Measures: The amount of substance, specifically the number of gas molecules.
   • Units: Moles (mol)

5. R (Ideal Gas Constant):

   • Measures: The constant that relates pressure, volume, moles, and temperature in the ideal gas law.
   • Value and Units: 0.0821 L·atm/(mol·K)

In summary:

• Temperature: K
• Pressure: atm, Pa, mmHg, Torr, psi (various units)
• Volume: L, mL, m³ (various units)
• N (Moles of Gas): mol
• R: 0.0821 L·atm/(mol·K)
