Practice question
Question
What happens to the pressure of an ideal gas if its volume is halved and temperature is kept constant?
Explanation
Boyle’s Law (Section 10.4) states PV = constant at constant temperature. If V2 = V1/2, then P2 = 2P1, so the pressure doubles. 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.
