(a)
Suggest why AC is the adiabatic part of the cycle.
[2]
Markscheme
ALTERNATIVE 1
«considering expansions from A» an adiabatic process will reduce/change temperature ✓
and so curve AC must be the steeper ✓
ALTERNATIVE 2
temperature drop occurs for BC ✓
therefore CA must increase temperature «via adiabatic process». ✓
