When you use the Format parameter, Windows PowerShell gets only the properties of the DateTime object that it needs to display the date in the format that you specify. As a result, some of the properties and methods of DateTime objects might not be available.y default, the date-time is displayed in long-date and long-time formats for the system locale. When you pipe a date to cmdlets that expect string input, such as the Add-Content cmdlet, Windows PowerShell converts the DateTime object to a string before adding it to the file.
= 1211 kJ mol-1. Therefore the molar heat of combustion of ethanol is 1211 kJ mol-1 (The molar enthalpy of combustion of ethanol is 1211 kJ mol-1). (Note that the enthalpy change for the reaction is negative because the reaction is exothermic, so the enthalpy change for the reaction is -1211 kJ mol-1, ÎH = - 1211 kJ mol-1)
The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).t is a known fact: Molar heat of sublimation = molar heat of fusion + molar heat of vaporization so, molar heat of vaporization = molar heat of sublimation-molar heat of f â¦ usion Mv = 62.3 kJ/mol - 15.3 kJ/mol Mv = 47 kJ/mol. 3 people found this useful.
