i think of that’s extra of a physics question. unique rigidity, assuming quantity is 1m³ rigidity = a million / quantity rigidity = a million / 1m³ rigidity = 1Pascal a million/3 quantity, considering that temperature is continuous Pressue = a million / quantity rigidity = a million / 0.333333333m³ rigidity = 3Pascal subsequently the rigidity is thrice the preliminary.
