Question

Derive the relation for work done in isothermal process​

Answer 1

Answer:In isothermal process the work done is .

Given:

As we know that work done during a process is the integral product of all the work done.  

Solution:

For one mole of gas, PV = RT  

So,

For the isothermal process, we have the temperature during the whole process be constant,  

Thereby we have,

Answer 2

Answer:

may be it will help

Explanation:

An isothermal process is a change of a system, in which the temperature remains constant: ΔT =0. This typically occurs when a system is in contact with an outside thermal reservoir (heat bath).and the change in the system will occur slowly enough to allow the system to continue to adjust to the temperature of the reservoir through heat exchange. In contrast, an adiabatic process is where a system exchanges no heat with its surroundings (Q = 0). In other words, in an isothermal process, the value ΔT = 0 and therefore the change in internal energy ΔU = 0 (only for an ideal gas) but Q ≠ 0, while in an adiabatic process, ΔT ≠ 0 but Q = 0.
