Phase Diagrams

Question 1

What is the temperature and pressure at which three phases are in equilibrium?

Answer 1

triple point

Question 2

What is a super-critical fluid?

Answer 2

 A super-critical fluid is a fluid like a liquid and a gas, but it has s density that can vary between the two extremes of the liquid and the gas

Question 3

Define triple point

Answer 3

the temperature and pressure at which three phases are in equilibrium

Question 4

Define critical point

Answer 4

at temperatures and pressures greater than this point, the definition of a liquid and a gas disappear and the substance exists as a super-critical fluid (SCF)

Question 5

What is the point at temperatures and pressures greater than this point, the definition of a liquid and a gas disappear and the substance exists as a super-critical fluid (SCF)?

Answer 5

critical point
