A sample consisting of 1.45 mol of perfect gas atoms is taken through the following cycle: step1 constant pressure, change in volume from 22.44L to 44.88L. Step2 Constant volume, change pressure from 1bar to .35bar. step3 pressure and volume change back to 1 bar and 22.44L. how do i calculate temperature,q,w,deltaU,deltaH,deltaS, and deltaA for each step of the cycle and the overall cycle?
Determine the mass of acetamide present per kg of water if the freezing point of this solution is 0 °C. (The freezing point of pure water is 0°C (exactly) at 1 atm pressure and the molal freezing-point-depression constant for water is 1.86°C/m.)
