5. Assuming that CO 2 is an ideal gas, calculate ∆H and ∆S for the following process: CO 2(g, K,1 bar) → CO 2(g,1000 K,1 bar) Consider 1 mol of gas and a reversible process. Given: C¯ P(T) = +×10−3T −×10−7T2 (units: J K−1 mol−1). Solution: Here refers to the standard state. For gases this is 1 bar pressure
Oct 13, 2019· Contributors; When an ideal gas is compressed adiabatically ((Q = 0)), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops. Adiabatic compressions actually occur in the cylinders of a car, where the compressions of the gasair mixture take place so quickly that there is no time for the mixture to exchange heat with its ...

560 – 580 (a.) Calculate Ä€ and ÄÛ for the transition of saturated bromine vapor from 560 to 580 K. (b.) Calculate ÄH (J) for the evaporation of 20 g of bromine at 580 K. (c.) Estimate the reference state (state of aggregation, temperature, and pressure) used to generate the
photograph accordingly. cm 323. Two narrow slits separated by mm are illuminated with [03] nm light. The peak intensity on a screen m away is W/cm2. What is the intensity at a distance mm from the center of the central peak?
Millimeters to Centimeters conversion. cm to mm conversion ►. 1 mm is equal to centimeters: 1 mm = cm. The distance d in centimeters (cm) is equal to the distance d in millimeters (mm) divided by 10: d(cm) = d(mm) / 10. Convert 20 millimeters to centimeters: d(cm) = 20mm / 10 = 2cm.
