Why melting and boiling are isothermal process

this is related to thermodynamics
Question asked by: shifalii

Asked on: 12 Mar 2010

Melting and boiling are state changes.

At melting then it goes from a solid to a liquid.

At boiling it, for instance water, goes from liquid to a gas.

At these stages then they absorb a great deal of energy from the environment in order to add energy to the molecules to allow the state change, therefore it makes sense that this is isothermic as energy from the environment moves to the molecules, there is no extra energy added or taken out.
