Both condensation from gas to liquid, and freezing from liquid to solid, do.

What change releases energy into its surroundings?
Exothermic reactions release energy into their surroundings. These reactions involve the release of heat, light, or sound, resulting in a temperature increase in the surrounding environment. Examples include combustion, oxidation reactions, and many types of chemical reactions.
Why does a change in teperature indicate that a change reaction may have occured?
Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
Where does an exothermic reaction release energy?
Into the surroundings.
When there is a chemical change is there an absorption of energy?
Yes, in a chemical change, energy is either absorbed or released. Endothermic reactions absorb energy from their surroundings while exothermic reactions release energy. The change in energy is often required to break and form chemical bonds during the reaction.
A change of state where energy is given off?
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
What is an ednothermic change?
An endothermic change is a process that removes heat energy from its surroundings.
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
Should melting butter release energy?
No, melting butter is an endothermic process, which means it absorbs energy from its surroundings to change from a solid to a liquid. This is why butter feels cold when it melts.
How do things absorb?
Things absorb when they take in and retain another substance or energy from their surroundings. This absorption process typically involves the transfer of molecules, particles, or energy into the material or object, leading to a change in its properties or state.
What is a exothermic change?
It is when something releases its energy to its surroundings do to a system.
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
What statement about the energy of a phase change is true?
Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts.
