Witch of the following phase changes is an exothermic change?
An exothermic phase change is one that releases heat to the surroundings. Among common phase changes, freezing (liquid to solid) and condensation (gas to liquid) are exothermic processes. During these changes, energy is released as the substance transitions to a more stable state.
What is the difference between endothemic and exothemic?
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
When energy leaves a substance what kind of change is that?
Energy loss is normally associated with a lowering of temperature and is a physical change. However, it can be caused by many other things such as nuclear change or chemical change, both of which are very different from each other and from temperature change.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
Is energy taken in during an exothermic change?
no, endothermic trust me it shows it in my book
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
Is energy is taken in during an exothermic change?
no, endothermic trust me it shows it in my book
How does energy changes as a substances?
Energy can change when a substance undergoes a phase change (such as melting or vaporization) or a chemical reaction. During these processes, energy is either absorbed (endothermic) or released (exothermic) as the internal structure of the substance changes. This energy change is due to the breaking or forming of bonds between atoms, resulting in a change in the overall energy content of the system.

Is the process of condensing exothermic or endothermic?
Condensation is considered a type of exothermic reaction. Condensation is something that is released, which means that is exothermic instead of endothermic.
When a substance loses energy to its surrounding environment?
exothermic
When energy leaves a substance what kind of change is that?
Energy loss is normally associated with a lowering of temperature and is a physical change. However, it can be caused by many other things such as nuclear change or chemical change, both of which are very different from each other and from temperature change.

What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the energy change when a substance is formed from its elements in their standard states. It represents the heat energy released or absorbed during the formation process. A negative value indicates that the reaction is exothermic, while a positive value indicates an endothermic reaction.
