Acontainer is divided by a partition into two equal volumes, v . one volume contains an ideal gas of n atoms, while the other volume contains a different ideal gas, also of n atoms. (d) calculate the change in entropy that occurs if the partition is removed. [8 marks] (e) explain what happens to the entropy when the partition is removed, if the two gases are the same

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
