Witrynabut first we need to convert the units for ΔS into kJ/K (or convert ΔH into J) and temperature into Kelvin. ΔS = − 284.8J / K( 1kJ 1000 J) = − 0.284.8kJ / K. T = 273.15 K + 25 oC = 298 K. The definition of Gibbs energy can then be used directly. WitrynaToughness. Toughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of toughness (for high-strain rate, fracture toughness) is that it is a property that is indicative of a material’s resistance to fracture when a crack (or other stress-concentrating defects) is present.
