Consider the following statements:
- During the conversion of solids into liquids and liquids into gases, the temperature remains constant.
- One cc of iron rod is heavier than one cc of chalk.
Which of the given statements is/are correct?
-
Only (1)
-
Only (2)
-
Both (1) and (2)
-
Neither (1) nor (2)
C
Correct answer
Explanation
Statement (1) is correct. The molecules of solids have the maximum force of attraction among them. For the conversion of solid into liquid, the given heat is used to break the strong bonds between them.
Statement (2) is also correct. Iron rod is heavier because the space between the particles of iron is very less, comparatively to the space between the particles of chalk.
