Use the phase diagram above to answer the questions below .( Remember that standard pressure is 1.00 atm and it’s used to find normal phase change temperatures.)

1: In which state/phase of matter is this substance at -10 °C and a pressure of 0.50 atm?

2: What phase change occurs as the substance at 0.75 atm is heated from 0°C to 25°C

3: The normal boiling point of a substance is the temperature at standard pressure (1 atm) in which a substance changes from the liquid to the gas/vapor state . What is the normal boiling point of this substance ?

4: The point on the phase diagram where the separation line between liquid and gas ends and the distinction between the liquid phase and gas phase disappears is called the ___________ . At this point ,no amount of pressure will cause the substance to condense into a liquid

5: What is the temperature and pressure of the triple point?
What phases are in equilibrium at this point ?

6: What phase change occurs as the substance at 0°C has its pressure dropped from 0.50 atm to 0.25 atm?

3: The normal boiling point of a substance is the temperature at standard pressure (1 atm) in which a substance changes from the liquid to the gas/vapor state . What is the normal boiling point of this substance ?

20 or 50 ?

For the phase diagram with has standard pressure equal to 1.00 atm the normal phase change temperatures found out.

What is a phase diagram?

A phase diagram is the way of representation of a substance, at different temperature and pressure, over a coordinate system.

1: The state/phase of matter is this substance at -10 °C and a pressure of 0.50 ATM- At this phase the solid state is in the equilibrium state with vapor state.

2: The phase change occurs as the substance at 0.75 atm is heated from 0°C to 25°C-

Deposition would occur.

3: The normal boiling point of this substance-

The normal boiling point of a substance is the temperature at standard pressure (1 atm) in which a substance changes from the liquid to the gas/vapor state.

In the attached phase diagram, the graph line has 1 ATM pressure at 20 degree and 50 degree Celsius.

4: The point on the phase diagram where the separation line between liquid and gas ends and the distinction between the liquid phase and gas phase disappears is called the Triple point. At this point ,no amount of pressure will cause the substance to condense into a liquid where three lines meets.

5:The temperature and pressure of the triple point-

The three lines meet at the point where the temperature is 10 degree Celsius and the pressure is 0.5 ATM.

The temperature and pressure of the triple point is 10 degree Celsius and 0.5 ATM respectively.

At the triple point all the three phases (solid, liquid and gas) are in equilibrium.

6: The phase change occurs as the substance at 0°C has its pressure dropped from 0.50 atm to 0.25 atm-

The phase change occurs as the substance at 0°C has its pressure dropped from 0.50 atm to 0.25 atm is from solid state to gaseous state.

For the phase diagram with has standard pressure equal to 1.00 atm the normal phase change temperatures found out
