Energy Transfers in Chemical Reactions

 

Changes in matter ] Importance of chemical reactions ] Chemical Reactions ] On-line practice ]

Energy can be converted from one form to another.

Example :

Chemical energy in crude oil

 

Oil is burnt to produce heat energy.  Heat is used for boiling water to produce steam.

Steam turns turbines (mechanical energy)

Mechanical energy is converted into electrical energy in the generators

Electrical energy produced by power stations is distributed to households and factories
