Understanding the Melting Point of Ice
The melting point of ice is a fundamental concept in science, particularly in chemistry and physics. It is essential to understand the conditions under which ice transitions from a solid to a liquid state.
What is Melting Point?
- The melting point is the temperature at which a solid becomes a liquid.
- For pure substances, this temperature is specific and consistent under standard atmospheric pressure.
Melting Point of Ice
- Ice melts at 0 degrees Celsius, which is equivalent to 273.15 Kelvin.
- This means that at 273.15 K, ice will start to turn into water if the temperature continues to rise.
Why Option 'C' is Correct?
- Option 'C' states 273.15 K, which is the accurate melting point of ice.
- The other options do not represent the melting point of ice:
- Option 'A' (373 K) corresponds to the boiling point of water.
- Option 'B' (277 K) is below the melting point and would still be solid for ice.
- Option 'D' (100 K) is far below the melting point and would not allow ice to exist in a liquid state.
Conclusion
- Therefore, the correct answer is option 'C' because it precisely identifies the melting point of ice at standard atmospheric pressure.
- Understanding this concept is crucial in various scientific applications, including studying phase changes and thermal properties of materials.
