Thermal energy is useful because it can be harnessed to generate electricity in power plants, heat our homes and buildings, cook food, and power industrial processes. It is versatile, abundant, and relatively easy to produce from various sources such as fossil fuels, biomass, and renewable energy like solar and geothermal.

How to find thermal efficiency in a system?
To find thermal efficiency in a system, you can use the formula: Thermal Efficiency (Useful Energy Output / Energy Input) x 100. This calculation involves determining the amount of useful energy produced by the system compared to the total energy input. The higher the thermal efficiency percentage, the more effectively the system converts energy into useful work.
Why is thermal energy produced not generally usable to do work?
Thermal energy tends to disperse in the environment, making it difficult to harness for useful work. This dispersion leads to an increase in entropy, reducing the available energy for performing work efficiently. Converting thermal energy directly into useful work often requires specialized and inefficient processes.
What is the efficiency of an engine that gives off thermal energy?
The efficiency of an engine that gives off thermal energy is determined by the ratio of the useful work output to the total energy input. It can be calculated using the formula Efficiency = (Useful work output / Total energy input) x 100%. A higher efficiency indicates that the engine is converting more of the input energy into useful work.
Which form of energy is the most randomized and most difficult to put to useful work?
Thermal energy is the most randomized form of energy because it manifests as random motion of particles in a substance. It is difficult to convert thermal energy into useful work because it tends to disperse and equalize, making it challenging to harness and direct for productive purposes.
What are the Useful types of output energy in a washing machine?
Useful types of output energy in a washing machine include mechanical energy for agitating and spinning the drum, thermal energy for heating water, and electrical energy for powering the control panel and motor.
What is the energy transformation that produces useful energy?
Thermal energy to electrical energy
Can thermal energy be made to do useful work?
Thermal energy is what is practically the ONLY source of energy for any work. Thermal energy cools, heats, runs motors, etc.
How to find thermal efficiency in a system?
To find thermal efficiency in a system, you can use the formula: Thermal Efficiency (Useful Energy Output / Energy Input) x 100. This calculation involves determining the amount of useful energy produced by the system compared to the total energy input. The higher the thermal efficiency percentage, the more effectively the system converts energy into useful work.
Where is useful thermal energy stored?
Useful thermal energy can be stored in various ways, such as in water reservoirs for hydropower, in underground caverns for compressed air energy storage, in phase change materials for thermal energy storage, or in hot water tanks for solar thermal systems. The stored thermal energy can be later converted into electricity or used for heating purposes.
What is the energy transfer in a light in the ceiling?
it is electrical to radiant and thermal I'm not sure about that answer i think it's electrical to light (useful energy) and thermal (which is the wasted energy)
Where is the useful thermal energy in a gas cooker stored?
Up your butt

Why is solar energy useful?
Because it is freely available and it doesn't damage the environment.
What is the efficiency of an engine that gives off thermal energy?
The efficiency of an engine that gives off thermal energy is determined by the ratio of the useful work output to the total energy input. It can be calculated using the formula Efficiency = (Useful work output / Total energy input) x 100%. A higher efficiency indicates that the engine is converting more of the input energy into useful work.
What is one of the energy released that isn't useful when coal is burnt?
One of the energy releases that isn't useful when coal is burned is thermal energy in the form of heat that is lost to the surrounding environment, rather than being converted into useful work or electricity.
What is a complete energy transformation sentence for a campfire?
t Campfires convert chemical energy stored in wood into thermal energy, which is useful for cooking food and staying warm.
How is uranium transformed into useful energy?
Uranium fission with thermal neutrons release an enormous quantity of energy; this heat is converted in electricity.
