Because heat gives off energy and is the first part of the energy cycle. Heat is the beginning of cold, and many other things.

∙ 11y agoAs work is easily converted into other forms as compared to heat energy hence it is high grade type of energy

What is the difference between the first and secong law of thermodynamics?
The first law of thermodynamic show that heat transfer is equal to work.But he does not give the direction as that system is consuming work or doing work. Whereas the second law of thermodynamic give the direction as (1) Heat can flow naturally from high temperature to low temperature.When heat is flowing from high temperature to low temperature he can produce work.(2)Heat can not flow naturally from low temperature to high temperature.for flowing heat from low temperature to high temperature he consume work. Second law of thermodynamic not only give the direction of heat flow but he also show entropy and quality of energy as high grade energy (mechanical work ) and low grade energy (heat).
What is the capacity to do work or produce heat?
Energy is the capacity to do work or to produce heat.
Which type of energy cannot do work in living organisms?
Heat Energy
Work and heat both involve of energy. fill in the blank?
Transformation of energy
What law of thermodynamics requires the work output of the engine to equal the difference in the quantities of heat taken in and released by the engine?
The first law of thermodynamics requires that the energy input to a system must equal the energy output from a system plus the accumulation of energy in a system. If no energy is accumulating then the energy input is the heat in and the energy output is the work and heat out.

What type of energy involve in work and heat?
Work is simply the transfer of energy. Heat energy is also known as thermal energy.
What is the capacity to do work or produce heat?
Energy is the capacity to do work or to produce heat.
Define heat of work and how it is computed?
Define Heat of Work and Explain how it is computed.Heat of Work (HOW) is the the amount of heat added to refrigerant during the compression process. The heat content of the refrigerant at the outlet of the compressor (high-side) is subtracted from the heat content at the inlet of the compressor (low-side). The unit of measurement is in Btu/lbAnswerThere is no such thing as 'heat of work'. Heat and work are two different, but related, things. 'Heat' describes energy in transit from a higher temperature to a lower temperature, whereas 'work' describes energy in transit when one form of energy is converted into another form. The difference between work and heat is a measure of the rise in the internal energy of an object.
What is the heat engine?
A heat engine is a system that converts heat to usable energy, particularly mechanical energy, which can then be used to do mechanical work
What is the study of relationships between heat work and thermal energy?
Thermodynamics is the study of the relationship between thermal energy and heat and work.
Why does heat consider as a form of energy?
Energy is defined as the ability to do work. When a body is supplied with heat,the body gains the tendency to do work.thus heat has the capacity to do work hence heat is considered as a form of energy
What is the thermal energy that flows from something at a high temperature to somethimg at a lower tempeature?
The thermal energy is stated as the first law of thermodynamics and its the sum of work and heat.
Why is heat form of energy?
It can do work.
What activities produces heat energy?
work produces heat
What device converts heat energy to work?
A heat engine.
Why heat cannot be converted into work and why work can be converted into heat?
A lower order energy cannot be completely coverted into a higher order energy. Heat energy is a lower order energy and work is higher order energy. Therefore it is not possible to convert heat into work without loosing some energy according to the second law of thermodynamics. But a higher order energy can be coverted completely into lower order energy and it will not violate the second law of thermodynamics.
