What is latent heat of sublimation?
When a substance is below the triple point, the equilibrium will be between solid and vapor rather than solid/liquid or liquid/vapor. Sublimation is the direct change from solid to vapor without any intermediate phase change. The latent heat of sublimation is the energy required to change a given quantity of solid into the vapor at equilibrium. It is analogous to (but not the same as) latent heat of melting (energy required to melt the solid to liquid) and latent heat of vaporization (energy required to change a liquid into a gas).
What happens when water changes from a solid to a liquid to a vapor?
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
WHAT TYPES OF PARTICLES HAVE THE LEAST AMOUNT OF KINETIC ENERGY ICE. SKIN WATER VAPOR OR AIR?
Ice particles have the least amount of kinetic energy compared to skin, water vapor, and air. This is because ice is a solid, where particles are tightly packed and have limited movement, resulting in lower kinetic energy. In contrast, water vapor and air consist of gas particles that move freely and rapidly, while skin, being a solid, still has more molecular motion than ice.
Which type of air can hold more water vapor-and-why?
Warm air can hold more water vapor than cold air because warm air molecules have more energy and are more widely spaced, allowing them to accommodate more water vapor molecules. Cold air is denser and has less energy, limiting its capacity to hold water vapor.
In which physical state would a water molecule have the greatest energy?
A water molecule would have the greatest energy in the gas (vapor) state because the molecules are more spread out and have higher kinetic energy compared to the liquid or solid state.

Does gas have the lowest thermal energy?
either solid liquid or gass or vapor
What happens when water changes from a solid to a liquid to a vapor?
When water changes from a solid to a liquid, it undergoes melting. When it changes from a liquid to a vapor, it undergoes evaporation. These changes are driven by increases in temperature and energy levels.
When does the energy of water increase?
The energy of water can increase if it is heated up, if it is placed under more pressure, if it changes phase, or if it flows faster. In phase change, increase of water's energy happens from: solid phase to liquid phase (melting), from solid phase to vapor phase (sublimation), and from liquid phase to vapor phase (evaporation). Increase in altitude also increases its potential energy.
How do you go from a solid directly to a vapor?
Solid to vapor is sublimation.
What is the major source of energy in the water cycle?
The answer is: It vapors into the form of, liquid,solid(ice) and vapor
Explain by kinetic molecular theory why ice is more dense then water vapours?
By looking at the states of matter ( solid ,liquid or gas) we can determine that a giben sample will have how much energy. Molecules in solid have least kinetic energy. Molecules in vapor (gas) have highest kinetic energy. Liquids have moderatee kinetic energy.
What happens to water vapor when energy is taken away?
If enough energy is taken away from water vapour, it will condense to form water (in liquid form). This is because a gaseous state requires more energy than a liquid state (and a liquid state requires more energy than a solid state).
What are the factors affecting the pressure?
Type of molecule: intermolecular forces between molecules are: * relatively strong, the vapor pressure will be relatively low. * relatively weak, the vapor pressure will be relatively high. Temperature: * higher temperature, more molecules have enough energy to escape from the liquid or solid. * lower temperature, fewer molecules have sufficient energy to escape from the liquid or solid.
How does thermal energy of water vapor change as the vapor condenses?
The thermal energy decreases as the vapor condenses.
How do solid and liquid water change to water vapour?
Sufficient energy is added to the molecule to break the inter-molecular bonds. First, in a solid, as energy is added, the bonds absorb the energy, and move more vigorously. So our solid heats up, and eventually, the bonds are broken completely free. We now have a liquid. As energy is added to the liquid, individual molecules absorb enough energy to break free of the surface, and evaporate off into space.
