Practice question
Question
What happens to the temperature of an ideal gas if its volume doubles at constant pressure?
Explanation
Charles’ Law states that at constant pressure, V/T = constant. If volume doubles (V2 = 2V1), the absolute temperature doubles (T2 = 2T1). As per NCERT, applying relevant law/formula with correct units and sign convention leads to It doubles. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
