Practice question

Given: In which process does Δ U = 0 for an ideal gas? These values define the system as per NCERT data. Formula: For an ideal gas, Δ U = 0 when temperature is constant (isothermal process), as internal energy depends only on temperature.. This is standard NCERT relation. Substitution & Calculation: Substituting values and simplifying step by step as per NCERT method. Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
