CAPE Physics Unit 1 · 2008 · Paper 2 · Question 6(b)(iii)

One mole of an ideal monatomic gas, Cᵥ = (3/2)R, is taken through the cycle represented by states 1 to 4 as shown in Figure 6. At state 1, P₁ = 1.01 x 10⁵ Pa, V₁ = 0.0225 m³ and T₁ = 273 K. At state 3, T₃ = 1092 K.

the energy added as heat during the processes 1 → 2 and 2 → 3

This question uses a figure or table from the paper — you'll see it when you practise.
