What else can I help you with?
Which of these processes have the same magnitude of energy change but are opposite in sign?
Endothermic and exothermic reactions have the same magnitude of energy change but are opposite in sign. In an endothermic reaction, energy is absorbed from the surroundings, while in an exothermic reaction, energy is released to the surroundings.
Is freezing an endothermic change or a exothermic change?
It is an exothermic change
What is the opposite of endothermic?
Exothermic. An endothermic reaction absorbs heat , while an exothermic reaction releases it.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
When energy is given off as heat the physical change is said to be?
Exothermic
Compare endothermic and exothermic?
An endothermic change requires heat, and an exothermic change releases heat.
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.
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
How do you use exothermic change in a sentence?
Jack recorded the exothermic change as the reaction progressed
What is a change in which energy is given off?
an exothermic change
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
Which phase change is an exothermic process?
Change of phase from gas to liquid to solid are exothermic reaction. Condensation, deposition and freezing are exothermic processes that undergo change in phase.
