Which of the statements given above is/are correct?i. Evaporation is p...
  • Statement i: Incorrect. Evaporation is caused by the absorption of heat, not the loss of heat.
  • Statement ii: Correct. Condensation occurs when moist air is cooled to its dew point, leading to the transformation of water vapor into liquid.
  • Statement iii: Incorrect. Sublimation is the process where a solid transitions directly to a gas, not the transformation of vapor into liquid.
  • Statement iv: Correct. Hygroscopic condensation nuclei, such as dust and salt particles, are essential for condensation as they attract water vapor.
Thus, the correct statements are ii and iv, making Option C (i, ii, and iv) the right choice.
