Fire. As soon as man learned to make fire he was able to cook food, have heat from the cold, and to share a campfire with others. This began the creation of tribes and society for early man and because he could eat cooked food and proteins his brain grew bigger allowing him to think beyond what animals could do making him superior to the animals he hunted.

Describe how the energy changes from a usable form to a less usable form in a building's heating system?
While producing heat energy is precisely the purpose of a heating system, once any kind of energy is converted into heat, it can no longer be converted back to other forms of energy - at least, not all of it.
What two forms of energy could best be used to increase the temperature of a sheet of copper?
heat and light
Where do passive solar heating systems and active solar heating systems get their solar energy?
they get their energy from the sun
Difference between isothermal and isobaric heating of saturated steam?
Isobaric heating is heating by adding only heat energy while maintaining the same pressure (isobar). Isothermal heating is heating by adding only pressure and no heat energy.
What energies come out of a kettle?
When a kettle is in use, the primary forms of energy involved are electrical energy and thermal energy. Here's how these energies are involved in the process: Electrical Energy: The kettle is connected to an electrical power source, and electrical energy is supplied to the heating element inside the kettle. The heating element is usually made of a resistive material, such as nichrome, which resists the flow of electricity, leading to the generation of heat. Thermal Energy: The electrical energy is transformed into thermal energy as the resistive heating element heats up. This thermal energy is transferred to the water inside the kettle, raising its temperature and causing it to boil. Heat Energy: The thermal energy generated in the heating element is transferred to the water, converting it from a liquid state to a gaseous state (steam) during the boiling process. Kinetic Energy: As steam is generated, it expands and exerts pressure, leading to the movement of steam molecules. This movement represents kinetic energy. Sound Energy: The boiling water and the release of steam can also produce sound energy. The bubbling and hissing sounds are examples of sound energy associated with the operation of a kettle. While electrical and thermal energies are the primary forms involved, the process of boiling water in a kettle can manifest in various forms of energy depending on the specific conditions and the environment

The earliest ones still around are stromatolites, but there were lots of earlier life forms.

Do all DNA descend from DNA in the earliest forms of life?
Yes. Our DNA has been passed on and changed/modified since the earliest forms of life.
What were the earliest forms of Chinese literature?
I think the earliest form is poem, because The Book of Songs is the earliest poetry anthology and the earliest literature.
How is geothermal gathered?
Geothermal energy is one of the many forms of alternative energy that come from renewable resources. This type of energy is gathered through heat collectors in the ground and then processed to produce many things including heating and electricity.
