Question

An ideal gas expands from volume V1 to V2. This may be achieved by any of the three processes, such as isobaric, isothermal and adiabatic. Which of the following statement is not true for ΔE?

Options

A.ΔE is the least in the adiabatic expansion.
B.ΔE is the greatest in the adiabatic expansion
C.ΔE is the greatest in the isobaric process
D.ΔE in isothermal process lies in between the value obtained under isobaric and adiabatic process.

Solution

ΔEadiabatic = Negative

ΔEisothermal = 0

ΔEisobaric = Positive
