Is friction a way to produce heat energy?
Yes. Whenever energy is wasted through friction, most of this wasted energy is converted to heat.
Is heat energy produced with the light energy in a torch?
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.
Why is heat the most common form of wasted energy?
Heat energy is the most wasted form of energy.
What energy transfer make the most heat?
Thermal energy
What two types of energy are most often wasted in devices?
your ...................
Most energy transformations produce what form of energy?
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
Is friction a way to produce heat energy?
Yes. Whenever energy is wasted through friction, most of this wasted energy is converted to heat.
Why heating appliances transfer the most energy?
Heating appliances are engineer designed to transfer the most energy. The manufacturer uses this design to produce the most effective heat transfer appliance to sell to their customers.

Why is heat the most common form of wasted energy?
Heat energy is the most wasted form of energy.
What transfer the most energy appliances that provide heat energy or appliances that provide other forms of energy?
appliances that provide heat energy
What energy transfer make the most heat?
Thermal energy
What is the largest amount of wasted energy in a transfer?
The situation really depends on the specific type of energy transfer. However, it is quite common that most of the wasted energy is converted into heat energy.
What two types of energy are most often wasted in devices?
your ...................
What type of energy is usually found as wasted energy?
Most typically waste energy takes the form of heat.
Two that produce the most energy?
The organisms that produce the most energy are plants. These organisms are autotrophs which means they can produce their own energy from the Sun.
Are energy star appliances easy to find in stores?
Yes, energy star appliances are easily found in most stores selling appliances. Just look for the Energy Star logo or ask a sales representative if you are having trouble finding one.
