Is liquid ammonia boiling a chemical or physical change?
Physical change.. think of it as it changing state not the substance
What happens when water vapor condenses into liquid water?
Condensation
When water vapor condenses into a liquid does temperature rise?
Yes. There is latent heat release when vapor condenses.
Which term is defined as the change in physical state form liquid to gas occurring throughout liquid?
The change in physical state from liquid to gas occurring throughout the liquid is called boiling. It occurs at boiling point of a liquid or when the pressure of the surroundings is reduced as per its boiling point. It boils with the use of vacuum pump and at high altitudes. Boiling Vaporization is the change in state from a liquid to a gas. Evaporation and boiling are the two types of vaporization. You are describing boiling. boiling A+: Condensation
Why is ethanoic acid a stronger acid in liquid ammonia than in aqueous solution?
Liquid ammonia is a more polar solvent than water
What is the temperature below which gas condenses?
The boiling point of the liquid to which the gas condenses at the pressure under which the gas condenses.
Temperature in which a gas becomes a liquid?
Each gas condenses at a different temp. as for water vapor it condenses at 212F or 100C
How does a ammonia purger work?
An ammonia purger removes air and noncondensables from the ammonia system by directing vapor from the condenser, where air collects, through cold liquid ammonia. This condenses the ammonia and separates noncondensables which are then removed from the system.
Why water has more boiling point than ammonia and hydroflouric?
Water is a liquid at room temperature; ammonia and hydrofluoric acid are gases.
What is a boiling point of substance?
The temperature at which it turns into a gas (usually the temperature when the liquid phase "bubbles" and vaporizes) also the temperature where the gas phase condenses to a liquid.
What is ammonia gas?
Ammonia (NH3) is a gas normally, the boiling point of liquid ammonia is -33 C at atmospheric pressure, but it can be stored as liquid at high pressure. Household ammonia is in fact a solution of NH3 in water. Early lasers (which were called Masers at the time) used ammonia gas for power.
Is liquid ammonia boiling a chemical or physical change?
Physical change.. think of it as it changing state not the substance
When vapour coming from a cover bowl of boiling water and the liquid condenses and drop back into the bowl what change occur?
physical change
Is energy absorbed or released when a solid melts a liquid vaporizes a gas condenses and a liquid melts?
Melting and boiling (vaporization) absorb energy, freezing and condensing release energy.
What happens when a gas condense?
a gas when condenses, it turns to a liquid. and also a liquid when condenses, it turns to a liquid. okay, we can take an example of domestic gas cylinders, it will in the form of compressed liquid and it condenses to gas when we use due to the changes in the atmospheric temperature. it will be at low pressure as a liquid and condenses to gas.
Why do water droplets form on a lid when boiling water?
The lid is cooler than the steam (water vapor) produced by boiling the water. When the water vapor contacts that cooler surface, it condenses into liquid water.
What is the working principle of a condenser?
A condenser rejects heat to the environment to turn vapor into liquid. Ideally a vapor enters the condenser as saturated vapor, meaning it's at the boiling point. The vapor condenses and leaves the condenser at saturated liquid (also at the boiling temperature).
