What is the steam being given off when the water boils is it water molecules or hydrogen molecules?
The steam produced when water boils is primarily composed of water molecules in the form of water vapor. This water vapor is the gaseous phase of water and is made up of individual water molecules that have escaped the liquid phase due to the heat energy applied during boiling. There are no hydrogen molecules present in the steam produced from boiling water.
Is conversion of steam to water an exothermic reaction?
Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
What happens to particle in liquid water when the water boils into steam?
Assuming they are non-volatile, solids in liquid water will remain in the water when it boils. This is the process of distillation, where the solids and non-volatile matter is separated from the water, and is left behind as the water evaporates off.
What type of energy is given off by the fossil fuels and used to boil the water?
Fossil fuels release thermal energy when burned, which is used to boil water in power plants to create steam. This steam then drives turbines to generate electricity.
Could you compare and contrast simple from steam distillation in terms of type of mixtures separated?
Simple and steam distillation are similar in that they use boiling to separate organic components. Simple distillation boils them off at their boiling points, then condenses them. Steam distillation uses water mixed with the compounds to lower their boiling points and avoid decomposing them by heat.
What does water give off when it boils?
Steam.
What is the steam being given off when water boils?
It's water vapour at first, water in it's gaseous form. It then condenses in the cooler air a bit later on as steam clouds - the droplets of water are formed.
When gas is given off as a liquid boils it is an example of a?
evaporation

When a gas is given off as a liquid boils it is a example of a?
This an example of vaporization.Vaporization is a physical change.
What is an example of matter that has gone through a physical change only?
A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
What is given off by the steam during condensation?
During condensation, steam gives off heat energy to its surroundings. This heat energy is released as the steam cools down and transforms back into liquid water.
When a gas is given off as a liquid boils it is an example of a?
When a gas is given off as a liquid boils, it is an example of a phase change. As the liquid temperature increases, the kinetic energy of the molecules rises until they break free from the intermolecular forces holding them in the liquid state, thus transitioning into the gas phase.
Is tap water distilled water?
No - distilled water is the vapour given off when water boils, which has then been condensed back into a liquid.
Why egg liquid does not become steam?
When you are frying an egg, there will be some steam given off by the egg as it fries; there is also lots of protein mixed into the egg liquid which is solidifying as it fries, because of chemical changes that it undergoes when heated, unlike water which just boils.
Is superheated steam suitable for air heaters instead of saturated steam?
No, superheated steam gives off little energy. Most of the heat given off by steam is the latent heat of condensation as it undergoes a phase change from vapor to liquid. Superheated steam could first be "desuperheated" by adding water until it reaches the saturation point, then used for heat transfer processes.
What gas boils off after nitrogen?
Argon does.
