Which form of energy is almost always produced during energy transformations?
Thermal.
Which form of energy is used to produce sound?
Sound is a form of energy... There may be many energy transformations before it becomes sound energy based on the instruments used. == == == ==
What theory states that if one form of energy can produce a second then the second form of energy should be able to produce the first form?
The theory of conservatio of energy
When energy is converted from one form to another how efficient is this transformation?
Anywhere between 0% and 100%. Different energy transformations have different efficiencies.
What form of energy does a motor produce?
Mechanical energy
What form of energy is produced as friction?
Friction can produce energy in the form of heat
What relationship exists between law of conservation of energy and energy transformations?
The law of conservation of energy states that energy cannot be created or destroyed, but only transformed into a different form.
What form of useful energy is a car designed to produce?
It is designed to transport you around, not produce energy.
What nuclear reaction combines gas to form helium and produce most of the suns energy?
nuclear fusion
What is the definition of energy transformations?
2. Energy can change from one form to another. This is called an energy conversion or energy transformation. • The Law of Conservation of Energy states that energy can change form, but it cannot be created or destroyed. Therefore, the total amount of energy stays the same. • In energy transformations, some energy is always lost to the environment as thermal energy. Examples of energy transformations and their uses: · A television changes electrical energy into sound and light energy. · A toaster changes electrical energy into thermal energy and light. · A car changes chemical energy from fuel into thermal energy and mechanical energy. · A flashlight changes chemical energy from batteries into light energy. · Solar energy is converted into electrical energy using solar panels. · Campfires convert chemical energy stored in wood into thermal energy, which is useful for cooking food and staying warm.
Does the heat produce energy or not?
Heat itself is a form of energy, so no.
What type of energy does a loudspeaker produce?
The energy is in the form of sound waves, which are moving air molecules, a form of kinetic energy.
