physical processes

Crude petroleum is pumped into the furnace where it is heated to a temperature of about 400 o C. Petroleum is converted to vapors in the furnace. The vapors of petroleum are fed into the fractionating column from the bottom. As the vapors enter the column, they rise up and gradually get c..

An adiabatic process is defined as one with no heat transfer into or out of a system: dQ=0. We can prevent heat flow either by surrounding the system with thermally insulating material or by carrying out the process so quickly that there is not enough time for appreciable heat f..

An isobaric process is a constant-pressure process. In general, none of the three quantities D U, Q and dW is zero in an isobaric process, but calculating W is easy nonetheless. W=p (V 2 -V 1 ) (isobaric process..

Here stored chemical energy is converted to electrical energy or current is drawn from the cell. The hydrogen ions go to the +ve electrode and SO 4 2 - to the -ve electrode. After giving their charges they react with the electrodes and reduce the active material to lead sulphate. Therefore, a..

In this section, we describe four specific kinds of thermodynamic processes that often occur in practical situations. These can be summarized briefly as no heat transfer or adiabatic, constant volume or isochoric, constant pressure or isobaric, and constant temperature or isothermal. For ..
