Formula and explanation

Formula: Δ U = W Applicable conditions: Adiabatic process (no heat exchange between system and surroundings, Q = 0 ). Explanation: There is no heat exchange between the system and its surroundings. Therefore, the work done on the system ( W ) is entirely converted into an increase in the system's internal energy ( Δ U ).
