Question
When water is heated to a temperature x, it gets converted into steam at temperature x by a process called R. And when steam at temperature x is cooled, it gets reconverted in to water at the same temperature x by a process called S.
  1. How much is the value of x in Kelvin?
  2. What is the process R called?
  3. What is the name of the energy absorbed during the process R?
  4. What is process S known as?
  5. What is the name of energy released during the process S known as?

Answer

  1. The value of ‘x’ in Kelvin is 373K.
  2. Vaporisation or boiling.
  3. Latent heat of vaporisation.
  4. Condensation.
  5. Latent heat of condensation.
