There are three states of matter solid, liquid and gas. What determines what state matter is in is how closely the matter's particles are to each other. When water particles are close together, making it dense, it's a solid (ice), when the particles space out a bit, becoming less dense, it becomes a liquid. When the particles space out even more from each other water becomes a gas.
No. If it was ice would float on water vapour!
They might have (close to) the same density because water expands when frozen OR heated. I'm not sure of the EXACT density for both.
Yes, if it's vapour then it is less dense
Yes it is.
Boiling converts the liquid water to water vapor. The bubbles are the water vapor escaping. As substances warm up, they become less dense, and the less dense something is, the less mass it has, so the water vapour rises to the top. Water in a pan or kettle bubbles like this because the source of heat is at the bottom, so the water near the bottom boils first. If you could somehow heat something from the top down, it probably wouldn't bubble.Water vapor is formed at the heated surface, and tends to coalesce on nucleation sites like an inflating balloon until it is carried to the free surface and released.
No, it is more dense. If it were less dense it would float.
more dense
liquid water followed by ice, finally followed by vapor. You can verify this by thinking about what happens when ice is in a cup of liquid water.
Ice cubes are less dense than liquid water, which is why they float.
less dense
Saturated air is more dense.
Water vapor is the least dense form of water because it is a gas, however, water is unique in the fact that its solid form, ice is less dense than its liquid form. This is because at freezing temperature the molecules of water expand into a crystalline lattice with a higher volume and equal mass.
Ice water is more dense than warm water.
water that is a liquid, evaporates into the air. and becomes dense forming moisture (water vapor)
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.
no
Ice is less dense than water
colder air doesn't collect as much water vapor
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.
A wooden block can be less dense than water.
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
