An ideal gas expands from volume V1 to V2. This may be achieved by any of the three processes: isobaric, isothermal and adiabatic. Which of the following statement is not true for Δ E?
Options:
Answer:
B
Solution:
Isobaric expansion: T rises, Δ E > 0. Isothermal: Δ E = 0. Adiabatic expansion: T falls, Δ E < 0. So Δ E is greatest for isobaric, least for adiabatic, and zero (in between) for isothermal. Statements (a), (c), (d) are true, so the statement that is not true is (b).
