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)
Calculate the molar heat capacity (C p) of titanium tetrachloride if the change in entropy when a 6.00 g sample of TiCl 4 (l) is heated from 25.0Â°C to 40.0Â°C is 0.154 J/K. When a 1.00 g sample of lead is heated from 298.2 K to just below its melting temperature of 600.5 K, the change in entropy is 0.0891 J/K.ne way of calculating Î´ S for a reaction is to use tabulated values of the standard molar entropy (SÂ°)The entropy of 1 mol of a substance at a standard temperature of 298 K. , which is the entropy of 1 mol of a substance at a standard temperature of 298 K; the units of S Â° are J/(molÂ·K).
