Question

Using the following heating curve, what line represents the melting point ["AB", "DE", "CD", "BC", "EF"] ?

What line represents the boiling point ["AB", "CD", "EF", "DE", "BC"] ?

Where would you use the specific heat capacity of a solid  ["DE", "EF", "AB", "BC", "CD"] ?

Specific heat capacity of a liquid  ["DE", "AB", "CD", "EF", "BC"] ?

Specific heat capacity of a solid ["AB", "CD", "DE", "EF", "BC"] ?

Where would you use the heat of fusion (Hfus) ["EF", "AB", "DE", "BC", "CD"] ?  

Where would you use the heat of vaporization (Hvap) ["EF", "DE", "BC", "CD", "AB"] ?

Time (minutes)

Explanation / Answer

horizontal lines are for melting and boiling

Since melting occur at lower temperature, the line BC is for melting and line DE is for boiling

slant line are corresponding to a particular phase

AB is solid

CD is liquid

EF is gas

1)

AB

2)

DE

3)

for solid: AB

4)

for liquid: CD

5)

for gas: EF

6)

AB

7)

DE
