Hope’s Apparatus (0798) Specifications : Height approx: 30 cm. Hope’s Apparatus is the simplest way to verify maximum water density at 4?C. The solid form of most substances is more dense than the liquid phase. But water plays an exception and with this apparatus you can determine the temperature at which water attains its maximum density. LAWS & PRINCIPLES INVESTIGATED : • Determination of water maximum density at 4?C • Determination of sea water density maximum at 2?C. Qty :
