Q8. A gas expands in a cylinder according to the relationship PV^1.3 = 1362. The initial volume of the gas is0.06 m^3 and the final volume of gas is 0.095 m³.

Calculate the work done by the gas during the expansion. (8)

Note: The work done by gas as it expands from V₁ to V₂ units of volume in W, where

B. Given dy/dx = 6x² + 2x - 1/3 - 3/x² and y = 60 when x = 3. Determine the value of y when x = 1. (8)
