Energy is neither absorbed nor released during expansion of ideal gas in vacuum. Why?
Energy is neither absorbed nor released during expansion of ideal gas in vacuum. Why?
In an ideal gas, there are no intermolecular forces of attraction. Hence, no energy is required to overcome these forces. Like, when a gas expends against vacuum, work done is zero as Pext – Hence, internal energy of the system does not change, there is no absorption nor release of energy during expansion of ideal gas in vacuum.
