Correct Option: A
U \(\alpha \frac{1}{V^3}\)
U = \(\frac{k}{V^3}\)
k = UV3
k = 81 x 23 = 81 x 8
When V = 3,
U = \(\frac{k}{V^3}\)
U = \(\frac{81 \times 8}{3^3}\)
U = \(\frac{81 \times 8}{27}\) = 24
U = \(\frac{k}{V^3}\)
k = UV3
k = 81 x 23 = 81 x 8
When V = 3,
U = \(\frac{k}{V^3}\)
U = \(\frac{81 \times 8}{3^3}\)
U = \(\frac{81 \times 8}{27}\) = 24
