What else can I help you with?
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
Which physical state changes are EXOthermic?
Freezing and condensing.
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.
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.
What Kinds of chemical changes?
Exothermic reactions. E.g. combustion, oxidation
An ionic bond will form only if the sum of the energy changes is?
exothermic
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
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.
What is the relationship between exothermic reactions and entropy changes in a chemical system?
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
