Physical and chemical changes can be either exothermic or endothermic changes?

The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear.

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.
Why is salt endothermic?
Not obligatory; the dissolution of sodium, calcium, potassium chlorides are exothermic.
Which physical state changes are EXOthermic?
Freezing and condensing.
Which occurs more often on earth physical changes or chemical changes?
what involves both chemical and physical change on earths surface
Is physical and chemical changes a scientific method?
Chemical and physical changes are part of methods applied in science.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
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.
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
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.
Why is salt endothermic?
Not obligatory; the dissolution of sodium, calcium, potassium chlorides are exothermic.
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
What are the ways that heat takes part in a chemical changes?
Heat can be involved in a chemical reaction that is endothermic(absorbs heat) or that is exothermic(releases heat)
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
Is burning a physical Change changes?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
