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.
What else can I help you with?
Condensation occurs when matter changes from?
gas to a liquid
When a liquid gains energy and changes in to a gas it is called what?
When a liquid gains energy and changes into a gas, it is called vaporization or evaporation. This process involves the molecules of the liquid gaining enough energy to overcome the intermolecular forces holding them together as a liquid.
How does water changes to solid liquid and gas?
Water changes from a solid to a liquid through melting and from a liquid to a gas through evaporation. The reverse processes are freezing (liquid to solid) and condensation (gas to liquid). These changes in state occur due to variations in temperature and pressure.
What phase changes require the subtraction of heat energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
When a liquid changes to a gas we say it?
When a liquid changes to a gas, we say it has vaporized or evaporated. This process occurs when the liquid's molecules gain enough energy to overcome the forces holding them together in the liquid state.
When a substance changes from a liquid to a gas energy is . When a substance changes from a gas to a liquid energy is .?
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
What do you call the change in state of matter from a liquid to a gas?
Condensation
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Identify to changes of state that require energy to be used and two changes of state that require the release of energy?
Changes of state that require energy: melting (solid to liquid) and vaporization (liquid to gas). Changes of state that release energy: freezing (liquid to solid) and condensation (gas to liquid).
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
Does potential increase or decrease when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
Condensation occurs when matter changes from?
gas to a liquid
When condensation occurs water changes from what?
Gas (water vapor in the air) to liquid (on the surface).
When water evaporatesheat energy changes it from?
liquid to gas
What energy changes liquid to gas?
AnswerHeat of vaporization.
Does kinetic energy increase or decrease when a liquid changes to a gas?
Kinetic energy increases when a liquid changes to a gas because the molecules in a gas have higher average kinetic energy compared to those in a liquid. When a liquid evaporates and becomes a gas, the molecules gain more energy and move faster, increasing their kinetic energy.
What is the process from a liquid to gas and gas to liquid?
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
