What else can I help you with?
What are two main forms of energy given off when paper burns?
heat and light and it comes from the reaction of the paper material and its combustion in the air.
Where is the majority of the nuclear energy that lands on Earth produced?
The Sun and other stars make heat & light by nuclear reactions. Nuclear energy is produced two different ways: In one, large nuclei are split to release energy. In the other method, small nuclei are combined to release energy.
What two energy transformations happen when you rub two sticks together and fire is started?
When you rub the sticks together, you convert kinetic energy (from moving the sticks) to internal energy, or heat energy - the sticks will warm up. When the heat energy is sufficient to overcome the activation energy of the combustion (activation energy = minimum amount of energy required to start a chemical reaction), the chemical energy in the sticks/whatever you are combusting is converted to heat and light energy
How does an atom in a liquid transfer heat?
Heat does not exist at the level of atoms, at the level of the atom its kinetic energy; which is only observed as heat at the macroscopic/bulk level.Atoms with more kinetic energy bounce harder against other atoms, transferring more kinetic energy to those atoms. This has two effects at the macroscopic/bulk level, where heat is observed:direct transfer of kinetic energy results in diffusion of heat, called conductionkinetic energy pushes the atoms further apart causing a reduction in density, enabling a process called convectionif the liquid is accelerating or in a gravitational field
The transfer of heat from one thing to another by direct physical contact?
Conduction is the transfer of heat throgh solid objects in direct contact. The other two types of heat transfer are convection (through liquids and gases) and radiation (through gases and a vacuum).
What are two other names for heat energy?
Thermal energy and caloric energy are two other names for heat energy.
What two names are given to the sun 's energy?
nuclear fusion
What type of energy can not converted to another type?
Heat. In fact you can convert part of the heat into other types of energy, only if there is a heat difference between two objects - but you can never convert all heat into other types of energy.
What two names are given to the sun's energry?
Solar energy and sunlight are two names given to the sun's energy. Solar energy refers to the radiant heat and light energy from the sun that can be converted into electricity, while sunlight specifically refers to the visible light that we see and feel.
Friction reduces efficiency because energy is lost as?
Heat due to the resistance between two surfaces moving against each other. This heat energy is not available to perform useful work, resulting in a decrease in efficiency.
What is a type of energy produced by friction?
Heat energy is a type of energy that can be produced by friction. When two objects rub against each other, the friction between them causes heat to be generated.
What are 2 forms of energy that may be absorbed?
Two forms of energy that may be absorbed are light energy, such as from the sun, and thermal energy, which is heat energy. When an object absorbs light energy, it can convert it into other forms of energy, like heat.
What two names are given the sun's energy?
Solar energy and sunlight are the two names given to the sun's energy.
What is the major way in which heat energy is spread through the atmosphere?
One way that heat energy is spread through the atmosphere is through radiation. Conduction and convection are two other ways that heat energy is spread through the atmosphere.
What are two names for the sun's energy?
Two names for the sun's energy are solar energy and sunlight.
Energy exists in two states what are they?
Energy exists in many more than two states, but two are light energy and heat energy.
Where there is friction there is?
heat. Friction occurs when two objects rub against each other, causing resistance, which produces heat energy. This phenomenon is the result of kinetic energy being converted into thermal energy.
