WebAt 20 °C, chloroform (CHCl 3) has a surface tension of 2.68 × 10 −2 J/m 2, while bromoform (CHBr 3) has a higher surface tension of 4.11 × 10 −2 J/m 2. Explain this observation … WebSurface tension is defined as the energy required to increase the surface area of a liquid, or the force required to increase the length of a liquid surface by a given amount. This … WebSurface tension is defined as the energy required to increase the surface area of a liquid, or the force required to increase the length of a liquid surface by a given amount. This property results from the cohesive forces between molecules at the surface of a liquid, and it causes the surface of a liquid to behave like a stretched rubber membrane. monarch dental ft worth
