The discontinuous phase transition of K 2 S 0 4 is described by a semi-empirical model that uses the elastic stiffnesses cn and the changes in volume and entropy associated with the order-disorder transition. Consideration of the elastic anomaly (existence of soft, damped longitudinal acoustic phonons) in K 2 S 0 4 removes the disagreement between transition enthalpies AHlr measured calorimetri...

We determine the relations of power product of physical quantities (PQs) by the generalized relation. Assuming the relations with two, three and four PQs to generalized relation separately, we find the corresponding general formulas. By ordering the exponent of physical constant in relations being zero or fit number, we gain many famous equations without factors such as mass-energy relation, fo...

This study was part of a larger effort called the transient dendritic solidification experiment (TDSE), which uses the well known Clapeyron effect to study transient effects in dendritic solidification. The transient behaviour was studied between well defined steady states using pressure mediated changes since it is almost impossible to study the transient behaviour during growth of a dendrite ...

The intensification of precipitation extremes in a warming world has been reported on a global scale and is traditionally explained with the Clausius-Clapeyron (C-C) relation. The relationship is observed to be valid in mid-latitudes; however, the debate persists in tropical monsoon regions, with the extremes of the Indian Summer Monsoon Rainfall (ISMR) being a prime example. Here, we present a...

To date, there are limited data on the thermal properties of secondary organic aerosol (SOA) components. In this study, we employed an experimental method to evaluate physical some atmospherically relevant compounds. We estimated thermodynamic SOA components, in particularly carboxylic acids. The molar heat capacity, melting point and enthalpy, vaporization enthalpy samples were determined via ...

Shape memory alloys are functional materials characterized by the effect of shape and superelasticity. Due to these properties, they widely used, particularly, in bioengineering, aeronautics, robotics civil engineering. The temperatures phase transformations influence external temperature strain rate on mechanical characteristics Ni55.75Ti44.15 alloy investigated this paper. is obtained differe...

Abstract As global warming continues, extreme precipitation events occur frequently in inland areas, seriously affecting human security and the ecological environment. Spatiotemporal evolution of as well response to climatic its mechanism were investigated by considering Weihe river basin a monsoon transition zone China research object. The results indicate that while annual average temperature...

The Clausius-Clapeyron relation and its analogs in other first-order phase transitions, such as type-I superconductors, are derived using very elementary methods, without appealing to the more advanced concepts of entropy or Gibbs free energy. reasoning is based on Kelvin's formulation second law thermodynamics, should be accessible high school students. After recalling some basic facts about C...

Abstract Increases in the severity of heat stress extremes are potentially one most impactful consequences climate change, affecting human comfort, productivity, health, and mortality many places on Earth. Heat results from a combination elevated temperature humidity, but relative contributions each these to changes have yet be quantified. Here, conditions for baseline specific humidity derived...

This study investigated the impact of sea surface temperature (SST) on extreme precipitation events in North Japan and its relation to synoptic weather patterns using large-ensemble climate simulations. Eight were identified by applying cluster analysis level pressure anomalies for selected days with derived from a 3000-year historical experiment. Interannual variability associated two specific...
