Why in Carnot cycle are used 2 adiabatic and 2 isothermal process? State Newton's law of cooling. If heat is thermal energy then what is cold? The quantity W in the First Law of Thermodynamics refers to the ___. a) work done on the system b) work done by the system c) change of...
What does each of the three variables in the expression for the first law of thermodynamics represent and what do the signs (positive or negative) mean for each variable? What is the second law of thermodynamics? a. Energy can be transferred ...
How does the early first version of M68K emulator work? What does it mean for a chord to be relative to the Dominant? Cisco control and management plane interfaces Why are ASCII escape sequences for ' treated differently in grep/sed/awk? How should I implement data acc...
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy. In particular, it describes how thermal energy is converted to and from other forms of energy and how thermal energy affects matter. Thermal energy is the energy a substance or sys...
An isothermal (constant temperature) line through the alloy's position on the phasediagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that's the horizontal yellow line on the diagram). ...
What does it mean when the calorimeter constant is negative? The initial temperature of a bomb calorimeter is 28.50 C. When a chemist carries out a reaction in this calorimeter, its temperature decreases to 27.45 C. If the calorimeter has a mass of 1.400 kg and specific heat of 3.52 J/(...
Thermodynamicsemerged in the 19thcentury, when scientists were building and improving steam engines, which use steam to help move an object such as a train. Understanding Equilibrium Most generally,equilibriumrefers to a balanced state that does not changeoverallwith time. This does not mean that no...
According to the convention does this mean you will do negative work on the gas if you pull OR push? The reason I'm getting so confused is that in the mark scheme, the answer is given as -5.74kJ. This means the work done ON the gas in an expansion is negative....
What does thermodynamics specifically assess about a system, and how useful is it? What does the law of thermodynamics state? Explain. For which process will the change in entropy of the system equal zero? a. isothermal b. adiabatic c. isobaric d. isochoric Which system has the higher entrop...
What type of process is involved in going from elements to compounds, and vice versa? What are the conditions to obtain an isothermal process in laboratory? Runners in the 100-m dash use starting blocks. Explain what this device does. PLEASE HELP. ...
