The word means: exo- "out" and -thermic "heat". So when heat is lost that is this sort of change of state. Endothermic is the opposite of exothermic.

When energy is given off as heat the physical change is said to be?
Exothermic
How do you change the state of matter?
Changing the state of matter is known as phase change, change in temperature creates phase change when the freezing or boiling point is reached.
Is the making of ice cubes an exothermic reaction?
exothermic. the energy flows out. exothermic. the energy flows out.
What type of change is freezing?
Physical Change
Is melting a change to metal physical changes?
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
Is freezing an endothermic change or a exothermic change?
It is an exothermic change
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.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What is an exothermic phase change?
condensation freezing and deposition
Is freezing an example of endothermic or exothermic change?
Exo
Which physical state changes are EXOthermic?
Freezing and condensing.
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.
What is a change in state from a liquid to a solid state?
Freezing is the change in state from liquid to solid.
How does the energy of a substance change during an exothermic change?
During an exothermic change, such as freezing, the substance releases energy to its surroundings.
Is freezing mercury a change of state?
Yes, freezing anything is a change of state.
Is freezing Endo or Exo?
Freezing is exothermic.
Freezing is a change of state true or false?
Yes, freezing is change of state, from liquid to solid. Freezing is a physical change, not a chemical change.
