Question

does the surroundings air becomes warm or cool when vapour phase oh h2o condense?explain

Answer 1

When vapour phase of water condenses to water, the surrounding air becomes warm. It is because water in vapour phase releases energy into the surrounding air when it gets converted into liquid phase.

Answer 2

Answer:

i) Condenses means phase change of vapour to liquid.

ii) When vapour phase of H2O condenses, the surrounding air becomes warm.

iii) During condensation, only slow moving water molecules are removed from air. leaving fast moving molecules behind.

iv) So, the average kinetic energy of the molecules in air increases.

v) Thus the surrounding temperature increases.

vi) So the surrounding air becomes warm.
