Identify the correct statements from the following:
(i) For adiabatic process, \(\Delta U = W_{\text{adiabatic}}\)
(ii) Work is a path function.
(iii) Volume is an extensive property.

Question

The difference of temperature in a material can convert heat energy into electrical energy. To harvest the heat energy, the material should have:

Answer 1

Step 1: Check each statement quickly.
(i) Adiabatic: q = 0, so \(\Delta U = W\) -- correct (IUPAC sign convention). (ii) Work depends on path (reversible vs irreversible give different values) -- correct. (iii) Volume scales with the amount of substance -- it is extensive -- correct.

Step 2: Conclusion.
All three statements are correct.
\[ \boxed{\text{All three are correct}} \]

Identify the correct statements from the following:
(i) For adiabatic process, \(\Delta U = W_{\text{adiabatic}}\)
(ii) Work is a path function.
(iii) Volume is an extensive property.
