A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adiabatic process, n = 1 an isothermal process, and n = 8 an isochoric process. Suppose 1 kg of dry air at 280 K and 100 kPa undergoes a polytropic expansion in which the pressure falls to 70kPa and the potential temperature increases by 10 K. Solve for(a) the value of n;(b) the change in internal energy of the air;(c) the work done by the air;(d) the heat absorbed by the air.
At T = O degrees Celsius and p = 1000mb, 1g of dry air receives during an isochoric process an amount of heat. It is then observed that its pressure increases by 50mb. What is the change of temperature of the air and what is the amount of heat absorb..
