When waste heat escapes into the environment it causes?
thermal pollution
What is damage that occurs when waste heat enters the environment?
thermal pollution
What is the term for extra heat given off by machines?
The term for extra heat given off by machines is "waste heat." It is the energy that is not used for the intended purpose of the machine and is instead released into the surrounding environment as heat.
What happens to most waste heat?
Most waste heat is dissipated into the environment through convection, conduction, and radiation. It can also be captured and converted into useful energy through technologies like waste heat recovery systems.
Does heat always rise in a given environment?
In a given environment, heat tends to rise due to the natural process of convection. However, heat transfer can occur in various directions depending on the specific conditions and materials present in the environment.
What must be present for heat to occur?
there must be atom and molecule movement for heat and a suitable environment for heat to grow, such as, it should already be hot where the heat is occurring
Why does heat energy become waste energy?
Heat energy becomes waste energy when it is not harnessed and utilized for productive purposes. In many systems, heat is produced as a byproduct of energy generation or industrial processes and is not effectively captured or transferred into useful work. As a result, the heat is simply dissipated into the surrounding environment as waste energy.
What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
What is waste heate?
waste heat is heat that is wasted, like cars waste 75% of heat
How does an endothermic reaction result in a decrease in temperature?
An endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature. This is because the energy required for the reaction to occur is taken from the surrounding environment, leading to a cooling effect.
What are three energy transformation that release heat into the environment?
Burning fossil fuels in a power plant to generate electricity releases heat as a byproduct. Combustion of gasoline in an internal combustion engine in a vehicle also releases heat. Incineration of waste materials in a waste-to-energy facility generates heat.
What temperature is required to transfer waste heat to the environment for an heat engine to be 100 percent efficient?
For a heat engine to be 100% efficient, it would require the hot reservoir (where heat is input) to be at a higher temperature than the environment to allow for heat transfer. However, it's not possible to achieve 100% efficiency due to the second law of thermodynamics, which states that some amount of energy will always be lost as waste heat during the conversion process.
