How is the state of water determined?
The number of bonds between molecules determines whether water will be a solid, liquid, or gas. In the solid state, water molecules have the maximum number of hydrogen bonds (4 per molecule), giving water the rigid characteristic of ice.
What are three different states of water?
Water can occur in three states: solid (ice), liquid, or gas (vapor).
What happens to water when it evaporates?
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Once water evaporates, it also helps form clouds.
What determines whether water is solid liquid or gas?
Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. The attractive intermolecular forces between particles that tend to draw the particles together.
What factor is most important in determining whether water is solid liquid or gas?
Temperature
What has the most control over water being a gas liquid or solid?
temperature
Which state of water has lowest density?
Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity. When water freezes at 0°C, a rigid open lattice (like a web) of hydrogen-bonded molecules is formed. It is this open structure that makes ice less dense than liquid water.
What is the most dense form of water?
As more material is dissolved in a gallon of water then that gallon will weigh more and be more dense—ocean water is denser than pure water. Heavy ice cubes sink to the bottom of a glass of water while the normal cubes float.
Is high density heavy or light?
If we take the same volume (one cubic centimetre) of foam, wood and concrete, we can see that each has a different mass. If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
What does a high density mean?
adjective. having a high concentration: entering a high-density market with a new product; high-density lipoprotein. (of a disk) having a large capacity for data storage: high-density DVDs.
Are more dense things heavier?
Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.
