1. indicates Consider the phase diagram shown below. The area labeled solid phase for the
substance 1. C. y E. y and z 1,000 800 P (tom) 600 100 10 0 10 20 30 40 50 60 T (C) Consider
the heating curve shown below. The slope of the corresponds to the heat capacity of the gas of
the substance. 2. segment A. AB B. BC C. CD D. DE E. EF liquid and gas solid and Equid
üquid A solid Heat added ()
Solution
(1) At low Temperature and low pressure , solid phase exists.
So , (A) w is correct
(2) Heat Capacity of Gas: The heat capacity specifies the heat needed to raise a certain amount of
a
substance by 1 K
So, option (E) EF is correct
