What is an advantage of fuel cells over lead storage batteries?
Electrical energy is continuously obtained.
What are the positive effects when trying to get geothermal energy?
Geothermal is heat energy obtained from below the earths surface. Once the infrastructure is setup to obtain this energy and convert it for use as heat or electrical energy, getting the energy is practically free.
How is energy obtained?
Energy is obtained by proteins/carbohydrates in your body.
Which Energy Converts Into Electric Energy?
Most of the electrical energy we use in modern society is obtained from generators - these convert movement to electrical energy. These, in turn, may get the energy either from 1. Heat (burning coal, or nuclear reactors); in this case, the heat causes water to evaporate, and the pressure pushes the machinery, or 2. Potential energy, stored in water.
What kind of energy do calories produce?
Calories don't "produce" energy; calories are a UNIT OF ENERGY.
How can you describe electrical energy?
Electrical energy is the energy in electricity - mainly in electrical currents.
Transformation of electrical energy to sound energy?
Electrical to kinetic to electrical energy in your cells
How formed electrical energy?
Electrical energy can be formed by solar, wind or hydro energy. This energy is transformed into electrical energy.
Electrical energy thermal energy?
The electrical energy of thermal energy is called kinetic energy. An example of electrical energy converted to thermal energy is a toaster drawing current from an electrical outlet.
Name two common energy conversions involving electrical energy?
electrical energy to heat energy or electrical energy into kinetic energy
What can be obtained from stored body fat and is needed to keep the body alive?
Energy (i.e calories). This stored fat can be converted easily into energy that your body can use - useful if there is no food available for a long time.
