1. Suppose you are an architect who designs homes in a fault zone. Why would learning about
earthquakes be important to you

2. What physical features should be visible in an earthquake model?

3. Which aspects of an earthquake are important to demonstrate in a working model? Explain.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

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?
