Question

Consider the thermodynamic process ABC on a closed system, which is an ideal gas, shown in the figure. The isotherms corresponding to T₁, T₂, T₃, T₄ are also shown on the graph. During the process,

(i) The mechanical work done by the system on the surroundings continuously increases, as the system is taken from A to C.

(ii) The internal energy of the system continuously increases, as the system is taken from A to C

• A. Only statement (i) is true
• B. Both (i) and (ii) are true
• C. Only statement (ii) is true
• D. Both (i) and (ii) are false

Answer 1

Answer: (B)

Both (i) and (ii) are true

Answer 2

Work done increases and temperature continuously increases
