Enthalpy vs heat capacity
WebFor a heat transfer system with ethylene glycol the circulated volume must be increased compared to a system only with water. In a 50% solution with operational temperatures above 36 oF the specific heat capacity is … WebChemical, physical and thermal properties of benzene, also called benzol. Phase diagram included. Benzene, C6H6, is a clear colorless to light-yellow liquid, flammable with a petroleum-like, aromatic odor. Benzene is less dense than water and is slightly soluble in water. Hence it floats on water.
