Abel observed in his practical lab class that the temperature does not change as long as water boils. Explain this observation giving suitable reasons.
b) Phosphorus melts at 44 0 C but lead melts at 325 0 C. Account for this difference in melting points.
c) Ice at 273K is more effective in cooling soft drink bottles than water at 273K. Steam at 373K causes more severe burns than water at 373K.
