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)
For H2O,the heat of fusion is 6.01 kJ/mol, and the heat of vaporization is 40.67 kJ/mol. 2)The fluorocarbon C2Cl3F3 has a normal boiling point of 47.6Â°C. The specific heats of C2Cl3F3 (l) and C2Cl3F3(g) are 0.91 J/gK and 0.67 J/gK, respectively.he heat required to convert 50.0 g of the compound from the liquid at 5.0 degrees celcius to the gas at 80.0Â°C is __________ kJ. 3)Ethanol (C2H5OH) melts at -114Â°C.
