At each temperature liquid water is in equlibrium with its vapour. the water so obtained is called a...water
Answers
Answer:
Consider the reversible process of water moving from the liquid phase to the gas phase:
H2O(l)↽−−⇀H2O(g)
At room temperature and atmospheric pressure, for which of the following scenarios does this process reach equilibrium?
A glass filled with water
A bottle of water after you poured half of the water out and recapped it.
A zip lock bag filled with water (no air).
Humid air in a zip-lock bag.
According to Wikipedia,
[...]chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal.
Answer:
for any pure liquid at one atmospheric pressure,the temperature at which the liquid and vapour are at equilibrium is called normal boiling point of the liquid
Explanation:
for water the boiling point is 100degreecelcius at atmospheric pressure.the boiling point of liquid depends on atmospheric pressure i.e the altitude of the place boiling point decreases at higher altitude
