What happens to substances as they lose or gain energy?
As substances lose energy, they tend to decrease in temperature and may change state (e.g. solid to liquid). Conversely, as substances gain energy, they tend to increase in temperature and may change state in the opposite direction (e.g. liquid to gas).
Do materials lose mass when they go from liquid to gas?
mass is never destroyed, nor can it be created. the same mass is still there, it is merely changing forms. density is another story.
What happens to energy in a substance when i change state?
As energy is absorbed, the energy moves up to other electron shell levels, but as the energy is released, it goes back to zero (ground state) and the energy is given off as light.
Does liquid lose chemical energy when frozen?
No, when a liquid freezes, it undergoes a phase change from liquid to solid but does not lose chemical energy. The energy required for freezing is used to reorganize the molecules in the liquid into a solid structure, but the chemical energy of the molecules remains the same.
What happens when a liquid changes into a solid?
When a liquid changes into a solid, it undergoes a process called solidification or freezing. The molecules in the liquid slow down and come closer together, forming a stable crystalline structure. This process releases heat energy as the molecules lose kinetic energy, resulting in the formation of a solid with a fixed shape and volume.
When a solid changes to liquid will it gain or lose energy?
It looses energy to the surroundings. When bindings brakes, energy is released.
When do most substances lose or gain energy?
Most substances lose or gain energy when their temperature changes.
Does a substance gain energy when it freezes?
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.
What happens when liquid solids or gas absorb heat?
the molecules gain or lose energy, the more energy these molecules have the easy it is for them to break the bonds holding them together, thus when you apply enough heat to a substance it changes from a solid to a liquid then from a liquid to a gas.
Do molecules gain or lose energy from melting?
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
Do particles lose or gain energy when changing from a liquid to a gas?
Particles gain energy when changing from a liquid to a gas as they absorb heat energy. This extra energy allows the particles to break free from the intermolecular forces that hold them together in the liquid state, enabling them to move more freely in the gas phase.
When condensation occurs dose a gas lose or gain thermal energy?
It loses energy. When energy is applied to any liquid the electrons start to orbit the nucleus faster meaning it's orbit enlarges causing the entire liquid to expand to the point of changing states. When a gas loses energy the electrons spin more slowly causing the gas to shrink to the point of turning to a liquid. So tecnically gas doesn't lose energy when it changes state but in order for it to change state it must lose energy.
What happens to substances as they lose or gain energy?
As substances lose energy, they tend to decrease in temperature and may change state (e.g. solid to liquid). Conversely, as substances gain energy, they tend to increase in temperature and may change state in the opposite direction (e.g. liquid to gas).
When compounds gain electrons they lose or gain energy?
Lose
Do materials lose mass when they go from liquid to gas?

Which changes of state should she place in the column titled lose energy?
The changes of state that involve losing energy are condensation (gas to liquid), freezing (liquid to solid), and deposition (gas to solid). These changes require the release of energy, typically in the form of heat, to facilitate the transition.
By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
A liquid changes to a solid when heat is removed, as the molecules lose energy and come together in a more ordered structure. A solid changes to a liquid when heat is applied, causing the molecules to gain energy and break free from their fixed positions. A liquid changes to a gas when heat is added, increasing the molecular motion and allowing them to escape into the vapor phase. A solid changing directly to a gas is called sublimation and occurs when the substance bypasses the liquid phase by gaining enough energy to transition from solid to gas.
