Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
1A thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
- ‘Unlike enthalpies, component entropies are nonadditive.’
- ‘We have modeled the closing kinetics and in so doing have obtained stacking enthalpies and entropies for single-stranded nucleic acids.’
- ‘Scanning calorimetry is used as a direct method to reveal the thermodynamic properties of phase transition like transition temperatures and enthalpies.’
- ‘Thermogram transition temperatures, enthalpies, and widths at half-height were determined using the software provided with the calorimeter.’
- ‘The internal energy of a system, like the enthalpy, is a state property, so it is fixed when the state of the system is specified.’
- 1.1The change in enthalpy associated with a particular chemical process.‘most compounds have negative enthalpies of formation’
- ‘First, the volume change and the enthalpy change of the protein can be determined in time domain without temperature variation or solvent variation method.’
- ‘The enthalpy, entropy, and free energy changes in the opening reaction of each basepair are determined from the temperature dependence of the exchange rates.’
- ‘The positive correlations lend support to the claim that a coupling free energy may reflect a state in which enthalpy and entropy components compensate for each other.’
- ‘In addition, melting requires significant amounts of extra heat, (in thermodynamic terms, the enthalpy of fusion), to break molecular bonds and cause a phase transition from solid to liquid.’
- ‘So, we can get useful work out of a system by reducing enthalpy or by increasing entropy (increasing the amount of disorder).’
1920s: from Greek enthalpein warm in, from en- within + thalpein to heat.
