Practice question

Given: What is the Fahrenheit equivalent of 50° C ? These values define the system as per NCERT data. Formula: Relation: t_F = 9/5 t_C + 32. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: t_F = 9/5 × 50 + 32 = 90 + 32 = 122° F . 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.
