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 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.
When condensation occurs water changes from what?
Gas (water vapor in the air) to liquid (on the surface).
Condensation occurs when matter changes from?
gas to a liquid
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.
When water evaporatesheat energy changes it from?
liquid to gas
Is it true that gas absorbs energy as it changes into a liquid?
When a gas changes to a liquid, it goes through the process of Condensation. This is when the gas cools and loses energy. Then the particles are forced to change state, from a gas to a liquid.
Is it true or false that a gas absorbs energy as it changes into a liquid?
True, when a gas changes into a liquid, it releases energy, typically in the form of heat. This process is called condensation.
