Heat can be produced through chemical reactions, such as combustion of fuels like wood or natural gas, which release energy in the form of heat. Alternatively, heat can also be generated through electrical means, where electric current flows through a resistor like a heating element in a toaster or an electric stove to produce heat.
What else can I help you with?
What are 2 ways to generate heat energy?
Two ways to generate heat energy are burning fossil fuels, such as coal or natural gas, to produce heat through combustion, and using electrical resistance heating, where electricity is passed through a resistive element to generate heat.
What are the three major ways of heat transfer?
The three major ways of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of materials, convection is the transfer of heat through movement of fluids (liquids or gases), and radiation is the transfer of heat through electromagnetic waves.
When a pendulum swing stops its energy is changed into what?
A pendulum will lose energy in two ways: 1. by friction with the air, 2. by friction in its supporting bearing. Both these energy losses will produce heat.
How does solar energy produce heat?
2 ways, in a solar collector the sun is concetrated to a focal point like burning things with a magnifying glass, witch is used to boil the water into steam and used to drive the generator. in a photo voltaic system heat is generated through resistance and is useless for the most part.
How does electricity come from candle?
I can think of three ways whereby a candle could produce electricity: 1). Heat water with the flame. When the water boils, use the steam to spin a turbine mounted to an electrical generator. 2). Place the flame close by a photovoltaic cell, which can convert a part of the candle's heat and light to electrical energy. 3). Place a pinwheel behind the candle flame, attached to an electrical generator, and wait for someone to come along and blow out the flame.
What are 2 ways to generate heat energy?
Two ways to generate heat energy are burning fossil fuels, such as coal or natural gas, to produce heat through combustion, and using electrical resistance heating, where electricity is passed through a resistive element to generate heat.
If a heat pump needs 2 kWh to produce 10 kWh of heat and this heat is converted to more than 2 kWh of electricity will this lead to an infinite circle of free energy?
A heat pump cannot produce more kWh than it is given.
What are 2 things homethermic animal can to do produce more heat?
A homeothermic animal is one that maintains its body heat from the inside, at a relatively constant temperature. Two ways it can produce more heat are to consume additional calories and to increase the level of activity.
What is the reaction which involves heat?
An example of a reaction that involves heat is combustion, where a substance reacts with oxygen to produce heat and light energy. This type of reaction is exothermic, meaning it releases energy in the form of heat.
List 2 ways rocks can be metamorphosed?
by heat and pressure on the rock
How many different ways can you represent the number 54?
2 ways
How many different ways can the letters in the word annually be arranged?
There are 8!/(2!*2!*2!) = 5040 ways.
How many ways does a kettle waste energy?
At least 2 ways, Sound (kinetic), heat and sometimes light.
What 2 things are required to produce metamorphic rock?
Heat and pressure are required to produce metamorphic rock from sedimentary or igneous rock.
What are the factors of 28 in three different ways?
Factors of 28 in three different ways are: 14*2, 7*4, 7*2*2 and remember also 28*1.
What are 2 different ways to mummify a body?
with chemicals and....
How do you name a triangle 2 different ways?
