In scientific terms give a definition of energy?
Energy in its most general definition can be thought of as the ability to do work. The type of work can vary-mechanical, electrical, thermal, nuclear, and so on. There is a good Wikipedia entry under Energy which is worth study.
Why does a wire get hot?
Leaving the power on would cause over heating of wires because the passing electrons with kinetic and electrical energy will transfer the energy as thermal energy when it touches the nuclei. This thermal energy will give the nuclei particles more kinetic energy and therefore causing more of a blockage for the electrons to flow.
Does the transfer of thermal energy by radiation require matter?
Now, this question has two answers. To give rise to, and to absorb, thermal radiation, matter is needed. Energy in the form of gravitational or electromagnetic fields neither emits nor absorbs thermal radiation. However, thermal radiation, an electromagnetic wave, does not need matter to transverse space.
What type of energy does steam give?
Thermal energy (heat) and Kinetic energy (movement).
What 2 forms of energy does fire give out?
Obviously its Thermal and Chemical Energy
Give an example of thermal energy?
When you rub two things together, like your hands, thermal energy is produced. This is a result of the friction.
What energy do all objects give off?
All objects give off thermal radiation.
When you exercise what energy does your body give off because of increased temperature?
It gives off thermal energy.
What energy does burning coal give?
Burning coal gives heat (thermal), light and sound energy.
Can you give an example of thermal energy?
Sure, just go touch the stove when it is on.
Give an example of heat energy?
Thermal energy can power up many things maybe billions sometimes thermal energy is powering up heaters (most of the time)
Why do trees transfer energy into the earth?
they dont they give oxygen
