Which chemical or physical change is an exothermic process?

Question:

Which chemical or physical change is an exothermic process?

Answer:

the combustion of gasoline

The chemical change that results in exothermic process is combustion of gasoline.

An exothermic reaction is a type of reaction that releases heat into the environment. The overall standard enthalpy change of exothermic reaction is negative.

Some examples of the exothermic process include the following:

• Reaction of strong acid and water
• Combustion firewood
• Burning sugar
• Rusting of iron
• Combustion of gasoline

Thus, the chemical change that results in exothermic process is combustion of gasoline.
