Question

Gas Laws:
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)
