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).
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.
When energy is added to a liquid and it changes into a gas it is called?
When enough energy is added to a liquid for it to change to a gas, the liquid has reached its _______________
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 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.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
What is a change of state in which energy is added as it changes state?
Solid --> Liquid. Liquid -> Gas. Solid --> Gas.
How can you change a gas to a liquid using thermal energy?
You have to do like the water cycle evaporation, where a liquid changes to a gas, condensation, where a gas changes to a liquid or little droplets and precipitation where it rains.
When condensation occurs water changes from what?
Gas (water vapor in the air) to liquid (on the surface).
The energy that gas changes to liquid?
The latent heat of condensation.
