1. What is Temperature of Gas given Average Velocity?

The Temperature of Gas given Average Velocity formula calculates the temperature of a gas based on its molar mass and the average velocity of its molecules, using fundamental gas constants.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T_g \) — Temperature of Gas (Kelvin)
• \( M_{molar} \) — Molar Mass (kg/mol)
• \( C_{av} \) — Average Velocity of Gas (m/s)
• \( \pi \) — Archimedes' constant (3.141592653589793)
• \( [R] \) — Universal gas constant (8.31446261815324 J/mol·K)

Explanation: This formula derives from the kinetic theory of gases, relating molecular motion to temperature through fundamental physical constants.

3. Importance of Temperature Calculation

Details: Accurate temperature calculation is essential for understanding gas behavior, predicting molecular motion, and applications in thermodynamics and fluid dynamics.

4. Using the Calculator

Tips: Enter molar mass in kg/mol and average velocity in m/s. All values must be positive numbers for valid calculation.
