Hello students, this question is based on the phase diagram.
00:05
Here t is the triple point where substance exhibits solid, liquid and gas i .e.
00:10
All phase at a time.
00:15
Here point 1 in diagram lies in solid state region so point 1 has solid phase.
00:27
When temperature increases, heat is added to substance.
00:30
Therefore from 1 to 2 there will be sensible heating of solid.
00:39
Point 2 shows latent heat solid to liquid.
00:43
Then 2 to 3 is the sensible heating of liquid and 3 to 4 is also sensible heating of liquid and point 4 shows latent heating of liquid to gas.
01:02
Then 4 to 5 shows sensible heating of gas.
01:06
Therefore the point 2 has solid -liquid phase, point 3 liquid phase, point 4 liquid -gas phase and point 5 shows gas phase...
