The melting point maximum against pressure is reported for poly(4-methyl-pentene-1): 270°C at 1.5 kbar. X-ray diffraction at high pressures shows no transformation up to 15 kbar at room temperature; the long-range order in the crystal remains unchanged with pressure while disorder of the...
For high density polyethylene (HDPE), a concentration of nitrogen at the polymer melting point of 10.4–35.7 mL(SATP) g(polymer) −1, in the pressure interval of 65–315 MPa, was calculated. 展开 关键词: Polyethylene Melting point Compressed gases High pressure DTA ...

Conversely, the freezing point can indicate the presence of solutes in a liquid, as solutes typically lower the freezing point of a solution compared to the pure solvent. 9 Environmental conditions, especially pressure, also play a significant role in these temperatures. The melting point of ice,...
The normal boiling point of Co is 2,870.00 degrees C. What is its boiling point in degrees C at a pressure of 147.7 mm of Hg if its heat of vaporization is 373.0 kJ/mole? How many joules of heat must be supplied to 4.3 grams of liquid water...
The pressure dependence of the molar volume was at constant temperatures close to the melting point in benzene. The molar volume of benzene was calculated using experimental data for the thermal expansivity for constant temperatures of 25°C, 28.5°C, 40°C, and 51°C at various pressures for...
The melting point of high Tsuperconductors was determined as a function of oxygen partial pressure. It decreased with the decrease in oxygen partial pressure. It was concluded that the melting is a kind of reduction reaction, in the form of Solid(I) → Solid(II)+Liquid+O. The enthalpy chan...
