please help solve all questions
(b) A monoatomic ideal gas initially at 300K is compressed at a constant pressure of 25 N/m² from a volume of 3.0 m² to a volume of 1.8 m³. In the process, 75 Jis lost by the gas as heat. (i) Determine a change in internal energy of the gas. [2 marks] (ii) Calculate the temperature of the gas at the end of the process. [2 marks] (iii) Determine the number of mole of the gas. [3 marks]
(c) A thermodynamic system is taken from state A to state B to state C and then back to A as shown in the diagram below. The vertical scale is set by p. = 40 pa, and the horizontal scale is set by V₁ = 4.0 m³. Calculate the work done by gas for a complete cycle ABCA, W [2 marks] C Ps Pressure (Pa) 0 T Volume (m³) V₂
