Question

. Can you give
example of any energy transformation where there is no dissipatuon of energy​

Answer 1

Answer:

yes

Explanation:

During conversion of energy from one form to another, all of energy does not get converted into one form of energy rather some of the energy is dissipated in the form of heat, light and sound energy. For example; when a ceiling fan is switched on, electrical energy is converted into kinetic energy. During this change, some of the energy is converted into heat energy which is evident from ceiling fan becoming hot. Following steps can be taken to reduce dissipation of energy:

• The machine should be subjected to continuous maintenance and timely repair.

• Lubricants should be used in machine.

• More efficient machines should be designed, e.g. a car with better mileage.

• Electrical appliances of higher star rating should be used.
