Final answer:
An in-progress fire inside a computer is classified as an Electrical fire, and it is considered a type of chemical change.
Step-by-step explanation:
If a fire started inside a computer being used by an employee, it would be considered an Electrical fire. This is because the fire would likely have originated from electrical components such as the power supply, wiring, or other electronic parts inside the computer. Electrical fires are typically classified as a type of chemical change, similar to other combustion processes such as the burning of coal or gasoline. These types of fires result from the chemical reaction of the electrical material with oxygen in the air, releasing energy in the form of heat and light.
