Since u and h depend only on the temperature for an ideal gas, the constant volume and constant pressure specific heats c v and c p also depend on the temperature only. For an ideal gas, the definitions of c v and c p are given as follows:. During a process from state 1 to state 2, the changes of internal energy and enthalpy are:. There are three ways to determine the changes of internal energy and enthalpy for ideal gas. This is a special relationship between c v and c P for an ideal gas. Also, the ratio of c P and c v is called the specific heat ratio,. By using the equation of state of ideal gas, the relations between P, v, and T are:. For some specific values of n, the process becomes isobaric, isothermal, isometric, and adiabatic, and they are summarized as follows:. For special processes such as the isobaric, isothermal, isometric, and adiabatic processes for ideal gas, using the average specific heats, the heat, work, and internal energy are given in the following table:.Interesting: Thermodynamics and Ideal Gas

| Thermodynamics and Ideal Gas | 20 hours ago · An ideal gas is contained in a cylinder. Initially the pressure, volume and temperature were P 1, V 1, and T 1. A spring with a spring constant k attaches to the piston as the figure. The area of piston is A. The gas expands against the spring by increasing temperature to at constant pressure T 2. What is the displacement? Let final. 2 days ago · If a thermodynamic process takes place at constant pressure, it is called an isobaric process. For example, such an isobaric change of state is observed when a gas is contained in a cylinder that is closed with a movable piston. When the gas is heated, it expands at constant pressure and the volume increases. 6 days ago · Ideal Gas Model: The ideal gas is defined as a gas which obeys the following equation of state: Pv = RT. The internal energy of an ideal gas is a function of temperature only. That is, u = u(T) Using the definition of enthalpy and the equation of state of ideal gas to yield, h = u + P v = u + RT. |
