Question

Which of the following level represents the solid phase of the substance?

• A. Level A
• B. Level B
• C. Level C
• D. Level D
• E. Level E

Answer 1

The correct option is A Level A

At origin temperature and heat both are zero , when heat is given to substance its temperature increases and it follows the level A, as more heat is given to substance its temperature does not increases more because its (level B) the change of state of substance, like that level D shows change of state. We know that when heat is given to a substance the order of state change is from solid to liquid and liquid to gas, therefore first level A will represent the solid phase of substance and level C liquid phase, level E gaseous phase.
