WebAug 17, 2006 · state function - it doesn't matter the path you take to get there, you will always arrive at the same spot. Example: If I want to have $1000 in my bank account, I can add 200/week until I have $1000 or I can add $750 one week, $500 the next week, and then take out $250 and I'll still have $1000. WebJan 30, 2024 · A state function is a function that is independent of the path taken but only depends on the initial and final states. For example enthalpy, internal energy, and entropy are examples of state functions since they don't depend on the path that is taken. Heat and work depend on what path is taken and therefore they are not examples of state ...

WebJan 30, 2024 · For example, one mole of ice the enthalpy is given as: ΔH = 6.01 kJ at 273.15 K ΔH = ΔU + pΔV Enthalpy can also be expressed as a molar enthalpy, ΔHm, by dividing the enthalpy or change in enthalpy by the number of moles. Enthalpy is a … WebCalculate the specific heat of the metal. (The heat capacity of the calorimeter is 12.4 J/°C.) CHEMISTRY Describe the interconversions of forms of energy occurring in these processes: (a) You throw a softball up into the air and catch it. (b) You switch on a flashlight. (c) You ride the ski lift to the top of the hill and then ski down.
WebThe thermodynamic properties whose values depend only upon the initial and final states of the system are known as state functions. A state function depends only on the start and endpoint, and not the path. Example of state function: Few examples of state functions are, Internal energy (U) Enthalpy (H) Entropy (S) Gibbs energy; Pressure ... WebIn thermodynamics the properties of a substance or the system is explained or based on various parameters of the system. One such parameter which is important to describe various properties is the path followed by the function. Chapter 6, Problem 8E is solved.

WebOct 22, 2015 · Examples of state function include (1) internal energy, (3) volume, and (4) pressure. This is because a state function is a value in which is dependent on the state of that particular system. The value of a change in a state function is always the difference between the final and initial values. It is important to note that the value depends ... WebSep 6, 2024 · Internal energy is a state function whereas, work done (reversible or irreversible) and heat are examples of path function. Q. Born and raised in the city of London, Alexander Johnson studied biology and chemistry in college and went on to earn a PhD in biochemistry.
