Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
thermodynamics, science of the relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.

In chemistry class, that would be a trick question (sorry!). In thermodynamics, heat has a very specific meaning that is different from how we might use the word in everyday speech. Scientists define heat as thermal energy transferred between two systems at different temperatures that come in contact.
- Couple things: 1. Be careful not to call it "Kelvin degree" or "degrees Kelvin." They are called "kelvins" (lowercase K). 2. The temperature in kel...
- q = CΔT and q = msΔT, so C = ms. C is the *total* heat capacity of the object. s is the *specific* heat capacity, i.e. the heat capacity per gram....
- Chemists can heat up substances to the point when they start to melt. At this temperature, the chemists can compare this value to a table of standa...
- zeroth law was discovered after the first law and other thermodynamic laws and because it was the most basic law they named it zeroth law.
- yeah, i would say you're right. heat is always spontaneously transferred from (object of) higher to lower temperature.
- In general, 'degrees' are found in units which are mainly arbitrary. Fahrenheit and Celsius are meant to be convenient instead of absolute. The sam...
- A thermometer shows the temperature because it measures (compare) the degree of agitation of its molecules in relation to the degree of agitation o...

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics, which convey a quantitative description using measurable macroscopic physical quantities ...
Thermodynamics is the science of the relationship between heat, work, temperature, and energy. The first and second laws were formally stated in works by German physicist Rudolf Clausius and Scottish physicist William Thomson about 1860. The third law was developed by German chemist Walther Nernst from 1906 to 1912.
Feb 20, 2022 · It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively.
8.2.2 Empirical Temperature; 8.2.3 Thermodynamic Temperature; The Second Law of Thermodynamics defines the transport of entropy in terms of the heat transfer and the thermodynamic temperature on the boundary where the heat transfer occurs. What precisely is a thermodynamic temperature? Because of its importance in the definition of entropy and ...
