Practice question

Given: What is the pressure exerted by 1 mole of an ideal gas in a 10-litre container at 300 K? (R = 8.31 J mol^{-1 K^{-1) These values define the system as per NCERT data. Formula: PV = μ R T, P = μ R T/V. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: P = frac1 × 8.31 × 30010 × 10⁻³= 2.493 × 10⁵ Pa approx 2.5 atm (1 atm approx 10⁵ Pa). Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
