How do evaporation and condensation change the form of water?
Evaporation changes water from a liquid to a gas by adding energy to break the bonds between water molecules. Condensation changes water from a gas to a liquid by removing energy so that the molecules come closer together and form liquid droplets.
What size is water vapor?
It depends on the amount of water boiled to make that vapor.
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)
What does codensation mean?
Condensation is the process by which a gas or vapor changes into a liquid. This occurs when the temperature of the gas is decreased, causing the molecules to come closer together and form a liquid state.
What is it called when water molecules in liquid vapor escape into the air as water?
This process is called evaporation. It occurs when water molecules gain enough energy to break free from the liquid phase and enter the surrounding air as water vapor.
Vapor pressure increases over a liquid in a closed container until?
Vapor pressure increases over a liquid in a closed container until the amount of vapor molecules rejoining the liquid equals the number leaving the liquid to form vapor. This is the characteristic vapor pressure of the substance.
What is the technical difference between water vapor and water?
Water vapor is the gaseous form of water, composed of individual water molecules. Water, on the other hand, refers to liquid water where individual water molecules are closely packed together. Water vapor is invisible to the naked eye and exists in the atmosphere, while water is the liquid form that we commonly use and see.
What is the relationship between water vapor air molecules temperature?
Whatever it is, gas, vapor, liquid, solid - the higher the temperature, the higher is the local agitation/speed of the molecules/atoms.
Molecules of a liquid to a molecule of water vapor?
During evaporation, molecules of a liquid gain enough kinetic energy to break free from the liquid surface and escape into the gas phase as water vapor. This process involves individual molecules transitioning from the liquid phase to the gas phase without the liquid boiling.
What is the relationship between vapor pressure and boiling point?
Vapor pressure and boiling point are related because they both involve the escape of molecules from a liquid into the gas phase. As vapor pressure increases, so does the boiling point. This is because a higher vapor pressure means more molecules are escaping the liquid, which requires more energy and thus a higher temperature to maintain the liquid state.
What is the relationship between the rate of evaporation and the rate of condensation of the vapor of a liquid in a closed container and has a constant vapor pressure?
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor. -KarkatHorns
What happens to the molecules of water vapor when the temperature of the gas cools?
the water vapor turns to liquid
What happen to the molecules of water vapor when the temperature of the gas cools?
the water vapor turns to liquid
What is equilibrium vapor pressure?
It is vapor molecules in equilibrium with a liquid in a closed system exert a pressure proportional to the concentration of molecules in the vapor state.
Do the fastest or slowest moving molecules break away from the surface of liquid water to form water vapor?
The fastest moving molecules are more likely to break away from the surface of liquid water to form water vapor. This process is called evaporation, and it occurs when molecules with higher kinetic energy overcome the intermolecular forces holding them in the liquid phase.
Is the vapor pressure of a liquid a linear function of temperature?
If the temperature of the liquid is raised, more molecules escape to the vapor until equilibrium is once again established. The vapor pressure of a liquid, therefore, increases with increasing temperature.
What is the main difference between the gas water vapor and the liquid water?
The main difference between gas water vapor and liquid water is their physical state. Water vapor is the gaseous form of water that is invisible, while liquid water is the condensed form of water that is visible and flows freely. Water vapor has higher energy and moves more freely compared to liquid water, which has a fixed volume and shape.
