Q: The temperature during solid melting-
  • A. Can increase or decrease according to the nature of the substance
  • B. Grows up
  • C. Decreases
  • D. Do not change
Correct Answer: Option D - When solid melts, the temperature remains the same, this is because the absorbed heat is utilized in breaking the forces of attraction between the particles and hence solid change to a liquid state without change in temperature.
