Below is a phase diagram for Carbon Dioxide. Use this diagram to answer the following question. In this example we will start the Carbon Dioxide out at a temperature of -20oC and 1 atm of pressure. If the pressure was raised to 100 atm of pressure while still staying at -20oC, what phases would the Carbon Dioxide change between?

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
