What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Is melting a penny an exothermic change?
Chemical, since it doesn't turn back.
Is phenol red a exothermic change?
Phenol red itself is not an exothermic change; rather, it is a pH indicator that changes color in response to pH levels. When it undergoes a change in pH, such as when it interacts with acids or bases, the process is typically not associated with a significant release of heat. Exothermic reactions involve the release of heat during a chemical reaction, which is not applicable to the color change of phenol red.
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.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
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.

Describe the two types of energy changes that occur in a chemical reaction?
An exothermic reaction and the change between potential and kinetic.
What change is exothermic chemical change?
A reaction in which heat is given out.
What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
Is a bicycle changes color as it rusts a chemical or a physical change?
It is a chemical change. Here oxidation of Iron occurs and being oxidation reaction, it is 'exothermic' reaction.Through it takes prolonged period and it is difficult to observe it, you can deduct it. As 'all' oxidation reactions are 'exothermic'.
Is melting a penny an exothermic change?
Chemical, since it doesn't turn back.

How do you use exothermic change in a sentence?
Jack recorded the exothermic change as the reaction progressed
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
