to the state of matter?

Answer 1

Phase Diagram

Question 2

shows a point where all the phases of matter co-exist at equilibrium?

Answer 2

triple point

Question 3

At what temperature and pressure would show the triple point of water?

Answer 3

at 0.01 °C and 0.006 atm

Question 4

What should be done to cause water to change from a solid phase to a liquid phase at a constant temperature?

Answer 4

increase and pressure

Question 5

best describes the slope of the solid-liquid boundary of water?

Answer 5

a negative slope due to its anomalous property
