The condenser in a steam engine is a chamber where steam is allowed to condense back into water, greatly reducing the pressure, which makes the stream engine run much better. If 0.82 kg of steam at 100 C is condensed into 0.82 kg of water at 100 C, by how much did the entropy of the steam/water change, including the sign to indicate increase (positive) or decrease (negative)

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
