What else can I help you with?
When 1 gram of water is evaporated the volume of the water vapor increases but the mass remains constant?
As the water is heated the amount of space that the water (now a vapor) increases in size (spreads out) but the mass (weight) is the same. If you could weigh all the vapor, it would weigh the same.
What form are molecules in water vapor?
Their form remains the same - water is water. However, the molecules are in a gaseous state/phase (rather than liquid or solid state/phase).
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.
How are ice water and water vapor different?
Water molecules in ICE are much "closer" packed. However, they are still vibrating a little bit. Water molecules in VAPOR are much "farther apart". They spread out as far as they can and bounce around in their container like jumping beans.
When is water in equilibrium with water vapor?
Water is in equilibrium with water vapor when the rate of evaporation of water molecules equals the rate of condensation of water vapor molecules. This typically occurs when the relative humidity in the air reaches 100% at a given temperature, known as the dew point.
Are water molecules the same as water vapor?
Water vapor is composed of water molecules with enough energy (temperature) to support that phase, as opposed to liquid or solid phases.
When 1 gram of water is evaporated the volume of the water vapor increases but the mass remains constant?
As the water is heated the amount of space that the water (now a vapor) increases in size (spreads out) but the mass (weight) is the same. If you could weigh all the vapor, it would weigh the same.
Is water vapor made of oxygen?
No. Water vapor is water in a gaseous state. It consists of water molecules each with one oxygen atom and two hydrogen atom.
What form are molecules in water vapor?
Their form remains the same - water is water. However, the molecules are in a gaseous state/phase (rather than liquid or solid state/phase).
How is water and water vapor alike?
the speed of the water vapor molecules can be decreased to produce ice
What size is water vapor?
It depends on the amount of water boiled to make that vapor.
How are ice liquid water and water vapor the same?
Solid (ice), liquid and vapor (steam) are (chemically) all of the same compound WATER with one chemical formula H2O, but in three different physical states of matter.
What is the difference between water vapor molecules and liquid water molecules?
They are made of different states of matter
How is water ice and water vapor alike?
the speed of the water vapor molecules can be decreased to produce ice
Are molecules that are farthest apart from each other called water vapor?
No, molecules that are farthest apart from each other are not called water vapor. Water vapor refers specifically to the gaseous form of water molecules. Molecules that are far apart from each other can simply be part of a gas phase.
How is the boiling of water and the cooling of water vapor a reversible reaction?
when water boils the molecules will get a bigger space inbetween them, which forms a gas (water vapor), when you cool down wator vapor the molecules will get closer together and form a liquid (water)
When water vapor is added to the air the density of the air is?
When water vapor is added to the air, the density of the air decreases. This is because water vapor molecules are less dense than dry air molecules.
