Question

Define condensation. What type of change, is it?

Answer 1

Condensation:

• Condensation is the change of the state of a substance from the gas phase to the liquid phase.
• ${\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$; Water vapors get converted to a liquid form by this process.
• Condensation is a type of physical change because during condensation no new substance is formed, only the physical state changes.
• It is also known as the reverse process of vaporization. For Example, water vapor condenses to form clouds.
• It is a type of reversible exothermic change.
