If at initial temperature, , is the internal energy and at higher temperature , is the internal ener — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

For an adiabatic rigid container, $q = 0$ (adiabatic) and $W = 0$ (constant volume). Therefore, by the First Law of Thermodynamics ($\Delta U = q + W$), the total internal energy change $\Delta E$ is exactly zero. The internal energy $E_1$ structurally equals $E_2$.
