Question
If two unequal masses of iron both have the same Internal energy, which of the following is true?
a. The larger mass is hotter
b.The smaller mass is hotter
c.The have the same temperature
On a phase diagram there is a triple point, where solids liquids and gasses all exist at the same temperature and pressure. If I decrease the temperature but increase the pressure from this triple point (to any substance but water) what phase would I be in?
a. Solid
b.Liquid
c.Gas
d.Depends on how much the temperature change is
Explanation / Answer
The smaller mass is hotter
Because = Q= mc T
Increasing the pressure will result into forming of liquid water acc to le chatelier's principle
For temp depends on how much change
