How do we use energy transformation in our daily lives?

1.The Sun transforms nuclear energy into heat and light energy.

2.Our bodies convert chemical energy in our food into mechanical energy for us to move.

3.An electric fan transforms electrical energy into kinetic energy.

Explanation:

1.The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun's surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).
