Question

An ideal gas is compressed to half its initial volume by means of several processes. Which of the process results in the maximum work done on the gas?(a) Isobaric(b) Isochoric(c) Isothermal(d) Adiabatic

Answer 1

In Adiabatic process, there is no transfer heat into the system.

Some adiabatic process

1.Expansion or comression of gas with insulated boundary.Ex.compression of gas in compressor

2.When expansion or compression take place at fast rate so that heat cann’t take palce into the system.Ex. when steam remove from pressure cooker, Blast of cycle tube

Answer 2

Answer:

d. Adiabatic

Explanation:

given: ideal gas is compressed to half it's initial volume

v°=v/2

The isochoric process is one in which volume is kept constant,meaning that work done by the system will be zero..

as we know, work done on the gas= area under curve

W(adiabatic) > W(isothermal) > W(isobaric)

[Here W is for workdone]
