- V. W. Th To %3D Room temperature T = 293 K V V. Vp The gas volume changes from Vp to Va at constant temperature T. The cartoon on the right shows a piston of gas undergoing this compression while submerged in a container of room temperature water, which acts as a reservoir. The initial state of this process is a piston containing 2 moles of a monatomic gas at Tc = 293 K (room temperature water) and volume V = a 1.0 m. The gas is compressed until V, = 0.2 m. During the compression, the heat bath of room temperature water maintains the temperature of the gas at T 293 K. Calculate the work done in joules by the gas during this process. Do not include units in your answer. Be careful to use the standard sign convention for work done by the gas. Write your numerical answer in normal form as described above in the instructions to this worksheet.arrow_forwardIn the project, the theoretical methods will be used to construct the property tables for ammonia using the Van der Waals Equation of state. You are required to find out the specific heats of the Van der Waals gas before performing the calculation. Consider the Van der Waals gas obeying the equation of state: Р C. RT a v-b v² where a and b are empirical constant to be determined assuming the critical point occur at inflection and stationary point on the p - v diagram. The critical pressure and temperature of ammonia are 11.35 MPa and 405.5 K respectively. Assume the universal gas constant, R = 8.314 J/mol K.
