a. A piston-cylinder device which containing air undergoes a cycle that made up of three processes as shown in Figure 1. The relationship for adiabatic process is given as PV* = C, where & is the specific heat ratio. If the air is an ideal gas with a mass of 0.5 kg and specific heat constant is assumed, calculate the heat transfer for each of the process (in kJ). Data for air: P Co=1.00 kJ/ /kg-K kair = 1.4 Isothermal 100 kPa- Adiabatic 0.002 m² 0.02 m² Figure 1 P-V diagram of the cycle

Atomic diffusion in solids

In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.
