Question

Q24. When water is heated without rise of
temperature, it consumes
(A) Sensible heat
(B) Enthalpy
(C) Latent heat
(D) Entropy​

Answer 1

Answer:

c is the correct answer

Answer 2

When water is heated without rise of temperature, it consumes latent heat (Option c)

• The energy change involved when a substance undergoes phase transition without any change in temperature, is called latent heat (or hidden heat).

• When water is heated, latent heat of vaporisation is consumed to overcome the intermolecular forces of attraction at a constant temperature.

• Entropy is the measure of of disorder of the system.

• Enthalpy is the heat change at constant pressure.
