Question

A)If you have a sample of ice at -15 oC and want to convert it to steam at 125 oC, what is the order of transitions that the sample goes through as heat is added.
      -       1.       2.       3.       4.       5.      

ice melts to liquid water


      -       1.       2.       3.       4.       5.      

water vapor increases in temperature


      -       1.       2.       3.       4.       5.      

liquid water increases in temperature


      -       1.       2.       3.       4.       5.      

ice goes up in temperature


      -       1.       2.       3.       4.       5.      

liquid water converts to water vapor

B)Put the following in order of increasing viscosity (smallest to largest).

      -       1.       2.       3.       4.      

CH3CH2OH


      -       1.       2.       3.       4.      


      -       1.       2.       3.       4.      

HOCH2CH2OH


      -       1.       2.       3.       4.      

H2O

Explanation / Answer

A) Order pf phase changes:

1) ice goes up in temperature

2) ice melts to liquid water

3) liquid water increases in temperature

4) liquid water converts to water vapor

5) water vapor increases in temperature
