Question

An ideal gas mixture filled inside a balloon expands according to the relation $P{V}^{2/3}=$ constant. The temperature inside the balloon is

• A. Increasing
• B. Decreasing
• C. Constant
• D. Can't be said

Answer 1

Answer: (A)

For the process with ideal gas $P{V}^n=$ constant. If expansion happens with $n>1$ then only the temperature decreases. But here $n=\frac{2}{3}$ , so here $n<1$ so temperature must increase.
