What has to happen in order for a gas to become a liquid in terms of energy?
Energy must be released-- A gas has a high amount of energy with it's atoms speeding around inside of it, a liquid has less energy, and a solid has the least. energy.
Does energy flow into or out of water when it is turning into ice?
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
Does water lose absorb heat energy when it condenses?
The change of state of water from liquid to vapor, or the reverse from vapor to liquid, involves a fixed amount of thermal energy per unit mass, this is called the specific latent heat. To evaporate liquid water to vapor, heat must be supplied, whilst in condensing vapor to liquid, heat is released. Similar rules apply to water when it changes from liquid to ice, or ice to liquid. You can look up the amount of the latent heat in physical tables.
Do molecules gain or lose energy from evaporation?
Water molecules gain energy in order to vaporize. That additional energy is needed in order for the water molecules to overcome the attraction that they have for the other water molecules in the liquid that they are part of. In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
What happens if energy is added or removed from a glass of ice water?
for a liquid to freeze , the attraction between the particles must overcome the motion of the particles.
In order to get liquid water to become water to become water vapor what must be energy?
Energy must be added to liquid water so that it reaches the boiling point, at which point the water will vaporize into water vapor.
When water changes from a liquid to a gas heat and energy do what?
When water changes from a liquid to a gas, it is evaporating or boiling. The "heat and energy" of the water molecules increases in the gaseous state. In fact, water molecules must pick up energy to change state from a liquid to a gas. Water molecules that are free to move as a gas have more kinetic energy than water molecules in a liquid form (as long as the liquid is not pressurized). The "heat and energy" of the H2O molecules that are now a gas is higher than that of liquid water.It should be noted that the thermal energy (heat) necessary to cause water to change state and become a liquid must come from somewhere. In evaporation, the energy necessary for the water molecule to escape from the liquid comes from the liquid. The liquid cools. We know that if we wet our finger and blow on it, it feels cool because evaporating water cools liquid water from which it escapes. That evaporating water has taken energy from the liquid water.In the case of boiling, water molecules take energy from liquid water, but the liquid water might not be cooling. It probably isn't as that liquid water is having thermal energy (heat) pumped into it by a heat source of some kind. Turn on a burner or element on the range under a pan of water and the water will begin warming until it's boiling. As water boils off, it is taking thermal (heat) energy with it, but the remaining water doesn't cool down as the heat source continues to add more thermal energy.

What takes place when water changes from a liquid to a gas?
To change state each water molecule must increase its speed (add heat energy) until it can escape from the liquid water around it.
Energy released as a gas changes to a liquid?
Energy isn't released; It is an 'endothermic' process. It requires energy for a gas to turn into a liquid. Example: Carbon dioxide is a gas as we encounter it in everyday life. To put this gas into a liquid (or even a solid), we must add pressure to the system. Adding pressure is a form of adding energy.

Why does liquid evaporate?
A substance changes from liquid to gas during evaporation because energy is absorbed. Evaporation is an important part of the water cycle.
What is happening to the particles and their energy when an object changes from a solid to liquid?
Energy is entering the system bc to change from solid to liquid there must be heat. Also the particles are now less dense and moving around more.
What is the heat of fusion for water is the amount of energy that must be absorbed for water to?
Melt.
What two changes of state must occur to produce to fog?
Fog occurs when the gaseous form of water (water vapor) begins to condense into water droplets (liquid water). So water is changing from a vapor (or gas) to a liquid.
What is the process called when water vapor in the air changes to liquid water?
Condensation.Related Information:For water vapor to become liquid water, it must loose energy, molecule by molecule. Often this occurs when water vapor contacts a cooler surface. In the atmosphere, water vapor condenses onto a small, cooler particle to form a very small droplet of liquid water, or condenses onto an existing droplet of water making it larger.
How does liquid turn into solid?
To turn from a solid to a liquid it must reach it's melting point by heating up. Examples: ice to water, rocks to magma. Every thing melts at a different temperature.
