the field of chemistry (o.k., and physics) that studies energy, work, etc. associated with various processes
Branch of physics dealing with time and energy and which connects living processes to the fundamental laws of nature.
The study of energy and its transformation.
A branch of science within physics which deals with the conformity of energy and material consumption in different processes. 1. The first principle of thermodynamics states that energy and material can be neither newly produced nor consumed. On the other hand, energy can be transformed from one form to another. Kinetic energy can, for example, be converted into electrical energy which can then be transformed into thermal energy. 2. The second principle of thermodynamics states that disorder, enthropy, increases in a closed system. Expressed in another way, this means that everything displays a tendency to spread on its own. It is possible to recreate order from disorder locally by supplying energy, but the problem is that there is always further increase in disorder somewhere else in the system.
The study of the relationship between heat, work, and other forms of energy.
the branch of physics concerned with very general properties of matter and energy. It also describes the macroscopic properties of matter in terms of the microscopic properties of its components.
Thermodynamics is the scientific study of the interconversion of heat and other forms of energy.
The physical theory of heat and energy distribution in the universe. The two important laws of thermodynamics state that the total energy of the universe is constant and energy can neither be made nor destroyed, and that the distribution of energy in the universe over time proceeds from a state of order to a state of disorder (entropy increase).
area of physics dealing with the relationship between heat and work
The science which studies the behavior of heat.
Gk. therme, heat + dynamis, power] The study of transformations of energy. The first law of thermodynamics states that, in all processes, the total energy of a system plus its surroundings remains constant. The second law states that all natural processes tend to proceed in such a direction that the disorder or randomness of the system increases.
The study of the transformations of energy. Contrast with: Kinetics See also: Energy Thermodynamics, First Law Energy, Internal Heat Work Enthalpy Entropy Thermodynamics, Second Law
The science and study of the relationships between heat and mechanical work. First Law: Energy can be neither created nor destroyed, but has a mass equivalent. Second Law: Heat cannot pass from a colder to a warmer body without the expenditure of energy; all systems tend to equilibrium. Third Law: At absolute zero, the entropy of a pure substance can be taken to be zero.
A branch of physics that deals with transfers and conversions of energy.
the study of the interaction of heat and matter.
Study of heat and its relationship to work.

the branch of physics concerned with the conversion of different forms of energy
study of energy relationships involving, heat, mechanics, work, and other aspects of energy and energy transfer.
The study of heat and energy flow in chemical reactions.
The study of laws affecting processes that involve heat changes and energy transfer. Heat transfer from one body to another; the link between heat and work and changes of state in a fluid all come within the field of thermodynamics, it is the prerequisite to analysis of work by machinery. There are essentially three laws of thermodynamics. The First Law says that heat is a form of energy and is conserved and any work energy produced in a closed system must arise from the conversion of existing energy, i.e., energy cannot be created or destroyed. The Second Law states that the entropy of any closed system cannot decrease and if the system undergoes a reversible process it remains constant, otherwise it increases. The result of this is that heat always flows from a hot body to a cooler one. The Third Law states that absolute zero can never be attained.
the field of physics that deals with heat, energy and work. Chemical thermodynamics is a subset of this discipline that deals with chemicals and how they interact.
Systematic theory on the relation between heat, work, energy and temperature. Thermodynamics is a sub-area of classical physics and evolved during the course of the 19th century. It turned out to be versatile and applicable to chemistry, biology and technology. Einstein dealt intensively with thermodynamics. In 1924, he described together with Satyendra Nath Bose how atoms behave close to absolute zero. The novel physical state is called "Bose-Einstein condensate".
The branch of physics dealing with the transformation of energy, especially of heat and other forms of energy.

theory of heat and energy distribution, especially the conversion of energy from one form to another; commonly expressed as three laws.
the science which addresses the relationships between heat and mechanical energy (work), and the conversion of either into the other; classical thermodynamics deals with the properties of systems in which temperature is a necessary coordinate; informational thermodynamics deals with the information conveyed by a communicating system; statistical thermodynamics deals with the organized complexity (order) of a structured system.

thermodynamic. The study of energy transfers and transformations.
a study of energy and its interactions.
Physics that deals with the relationships and conversions between heat and other forms of energy.
Thermodynamics is the study of the conversion of energy between heat and other forms, mechanical in particular. There are many processes that convert energy from one form to another. For example burning wood converts chemical energy (in the wood) to heat; turning a hydroelectric generator converts the kinetic (motion) energy of the water into electrical energy. There are two laws which we can use to help understand processes like these: The first law of thermodynamics says that energy is conserved, it is neither created nor destroyed but can change form. The second law of thermodynamics says that systems always tend to states of greater disorder -- this is another way to say that the entropy always increases. In terms of energy conversions this means that they can never be 100% efficient. Some portion of the energy involved in a conversion will inevitably be lost to the surroundings as heat.
A study of the transformation of energy into other manifested forms and of their practical applications. The three laws of thermodynamics are: Law of Conservation of Energy: Energy may be transformed in an isolated system, but its total is constant. Heat cannot be changed directly into work at constant temperature by a cyclic process. Heat capacity and entropy of every crystalline solid becomes zero at absolute zero (0 degrees Kelvin).
The study of the energy transfers accompanying physical and chemical processes.

Study of the processes that involve the transformation of heat into mechanical work, of mechanical work into heat, or the flow of heat from a hotter body to a colder body.
This deals with the transfer of heat into energy and energy into heat.
A study of the transformation of energy from one form to another, and its practical application. (see Law(s) of Thermodynamics above).
The science of heat energy and its transformations to and from other forms of energy.
Thermodynamics (from the Greek thermos meaning heat and dynamics meaning power) is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics. Roughly, heat means "energy in transit" and dynamics relates to "movement"; thus, in essence thermodynamics studies the movement of energy and how energy instills movement. Historically, thermodynamics developed out of the need to increase the efficiency of early steam engines.
