In steam are the forces between molecules the same as the forces between the molecules in water?

No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.

What is the steam being given off when the water boils is it water molecules or hydrogen molecules?
Steam is water molecules in vapor form
What are the primary forces of attraction between water molecules in H2O?
Hydrogen bonds
Attractions between water molecules are called?
"van der waals" forces.
Does air turn into water?
No, when water boils it evaporates into single water molecules. We can see the cooler of these as they condense into steam. Steam or water vapour is the water molecules re-condensing into water droplets.
What is binding buffer?
It contain acetate and chaotrope. It disrupts the intermolecular forces between water molecules,allowing proteins and other macromolecules to dissolve more easily.
Are there hydrogen bonds between molecules in steam?
Water is a polar substance. In liquid water, this gives rise to hydrogen bonds between molecules, making it structurally more compact. However when water is heated up to steam, those hydrogen bonds break up and the molecules cannot be maintained globally as aggregates. The forces in play in steam are of collisional type and the polarity of the molecules does result in short-range attractive forces yielding negative second virial coefficients but in no way the molecules arrange themselves to conform to a hydrogen-bonded structure. The probability of simultaneous collision between several molecules though rare in steam may become important at high pressures below the critical point, but should not be confused with the structuration between neighbouring molecules in liquid water where hydrogen bonding takes place due to the closeness between water molecules. What is sure is that there is no hydrogen bonds above the critical point of steam. In steam hydrogen bonding is just not taking place for the molecules are too distant from each other. Collisional binary encounter does not generate hydrogen bonding!!!
Do the fastest or slowest moving molecules break away from the surface of liquid water to form water vapor?
The fastest moving water molecules will break away from the surfrace of the water to form water vapor, they have the energy to overcome the attractive forces between molecules.
What is the steam being given off when the water boils is it water molecules or hydrogen molecules?
Steam is water molecules in vapor form
Why does drop of water appear like pearl?
A drop of water appears like a pearl due to the cohesive forces among its molecules. Forces of attraction between water molecules and other molecules called adhesive forces.
What causes steam?
steam is water evaporating. It is caused when water molecules have enough energy to break free from the electromagnetic interactions that holds all the water together as a liquid. Short form - steam is water so when it is hot it turns into gas.
What are the primary forces of attraction between water molecules in H2O?
Hydrogen bonds
Attractions between water molecules are called?
"van der waals" forces.
What types of bond is found between different molecules of water?
The most significant force holding water molecules together are the hydrogen bonds. Water also has dipole-dipole forces, and dispersion forces as well.
What causes of the water to evaporate?
The intermolecular forces between water molecules are lowered at the water surface and some molecules escape in the atmosphere. Evaporation is increased by temperature.
What happenes to water when you boil it?
Its molecules gain more and more energy from the heat and they start moving more faster. Eventually they gain enough energy to overcome the bonds that hold them togather and become water vapour or steam.
Does air turn into water?
No, when water boils it evaporates into single water molecules. We can see the cooler of these as they condense into steam. Steam or water vapour is the water molecules re-condensing into water droplets.
