Calculation Formula

Internal Energy (U) = \(\frac{3}{2} nRT\)

Where:
U = Internal Energy
n = Number of Moles
R = Universal Gas Constant (8.314 J/(mol·K))
T = Temperature in Kelvin

Result

Internal Energy (U) = 0.00 J

Internal Energy Calculator Usage Guide

Learn how to use the Internal Energy Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the number of moles (n) of the gas.
  2. Enter the temperature (T) in Kelvin.
  3. Click the "Calculate" button to compute the internal energy.
  4. The result will be displayed in joules (J).

Working Principle

The internal energy of an ideal gas is calculated using the formula \( U = \frac{3}{2} nRT \), where \( U \) is the internal energy, \( n \) is the number of moles, \( R \) is the universal gas constant (8.314 J/(mol·K)), and \( T \) is the temperature in Kelvin. This formula assumes that the gas is ideal and that the internal energy is primarily due to the kinetic energy of the gas molecules.
