Solidification in heat packs: I. Nucleation rate
... For predicted numbers well below unity, such as for the stable subcooled states in this work, there will almost always be zero incipient nuclei present, very occasionally one, and effectively never more than one. Neglecting any probability of finding more than one incipient nucleus means the value o ...

... For molar specific heats of gases we can write C=1/n (dQ/dθ) where n is the number of moles And n =m/M where M is the molecular mass and m is the mass of a gas therefore C= M/m (dQ/dθ) J/mole-K Mayer’s equation: CP-CV =R where R is the universal gas constant its value equals to 8.31 J/mole-K The rat ...

... Thermal mass must be located where passive solar gains exist. Otherwise it will absorb heat from the room in winter, making it cold. The best place for thermal mass is in floors and walls that receive direct solar gains in winter. Glass must be north-facing and shading designed so as to protect from ...

Some general information about thermodynamics
... Many of the principles of thermodynamics and heat engines can be visually displayed on a pressurevolume (pV) graph. The pressure is displayed on the y axis and the volume on the x axis. Common units for pressure would be psi or kilopascals. Volume is often displayed in mL or m3. The pressure, number ...

Figure 5 also reveals that there is nearly no difference of thermal expansion coefficient between different high pressure when the temperature is below around 382°C. Above this temperature, the thermal expansion coefficient of samp ...
