4.1. A liquid flows into a 5 m^3 tank at a flow rate of 3 kg/s and leaves at a rate of 2 kg/s. Initially, there is 1 m² of liquid in the tank.
(a) Classify the process as transient or steady-state
(b) Classify the process as batch, semi-batch, or continuous
(c) Write a mass balance for the process in terms of the general balance equation

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

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?
