QUESTION 4 (25 Marks) (a) (b) (c) A plate has side p=4-2x. Compute the mass along the x-axis from x=0 to x=2 using integration. [Hint: Mass = Area of plate] The entropy change As, for an ideal gas is given by the following formula: dV V₂ dT T As = T₂ [c, -R T₁ (7 marks) where T is the thermodynamic temperature, V is the volume and R = 8.314. Compute the entropy change when a gas expands from 1 litre to 3 litres for a temperature rise from 100 K to 400 K. Given that C₁ = 45+6×10¯³T+8×10T². (11 marks) Given the energy of an inductor is W = ſt² lnt dt, compute the energy, W in terms of t using integration by parts. (7 marks)
