What does it mean to have high thermal energy?

It mean, it had high temperature difference to the surrounding. Quality of thermal energy is upon the temperature due to thermodynamics efficiency. At same thermal energy of 100 kJ refer to 0 oC ambient, a hot bath of 100 oC may have maximum theoretical thermal efficiency of 27% or 27 kJ usable but a hot steam of 200 oC may have maximum theoretical thermal efficiency of 42% or 42 kJ usable.


What is meant by thermal engineering?

Thermal engineering means the conversion of heat energy between mediums and into other usable forms of energy. Most of the energy from thermal sources is converted into chemical, mechanical or electrical energy. In order to achieve this, thermal engineers are experts in heat transfer. Some areas a thermal engineer may specialize in include solar heating, boiler design (heating, ventilation and air conditioning).


How is cellular respiration to photosynthesis?

Energy produced in photosynthesis is put into a usable form through cellular respiration.


Is glucose is an unusable form of energy produced through photosynthesis True?

Yes it is true. It is a usable product.


How does oil covert into usable energy?

When it burns, it produces heat. So it produces thermal energy. Oils are also used in hydraulic systems, meaning they can be used to facilitate the production of fluid energy.


How is photosynthesis is related to cellular respiration?

Energy produced in photosynthesis is put into a usable form through cellular respiration.


What is solorelectricity?

I think you tried to mention solar electricity. It the electricity produced from the sun's energy called solar energy. The sun's energy is caught by the solar cells which then convert them to electrical energy to produce electricity._______________________________________________________________Solar electricity means:Photovoltaic electricitySolar thermal electricityA photovoltaic system (informally, PV system) is an arrangement of components designed to supply usable electric power for a variety of purposes, using the Sun (or, less commonly, other light sources) as the power source.Solar thermal energy (STE) is a technology for harnessing solar energy for thermal energy (heat) requirement in industries, residential sector and commercial setup.


How is friction related to the law of conservation of energy?

When an object slows down because of friction, its energy is not lost but merely transferred to thermal energy. Since energy naturally disperses as much as possible, the thermal energy gets dispersed throughout the atmosphere. Even though the energy is no longer usable it is still conserved. *see the second law of thermodynamics


Is glucose is a usable form of energy produced through photosynthesis True?

yes you ar true. it is the main product of photosynthesis.


What is the difference between usable energy and the total amount energy?

usable energy changes, while total energy does not


Is this sentence correct photosynthesis is the process of which plants sunlight into energy?

Light energy is captured by the chloroplast, then, glucose is produced and then consumed, so it's a usable chemical energy available in the cell.


What is required to change light into energy that is usable?

Light energy is already usable - please clarify.
