An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg-K.

![### Otto Cycle Problem Statement
An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is \( R = 0.287 \, \text{kJ/kg·K} \).
#### Task
Determine the thermal efficiency. (You must provide an answer before moving on to the next part.)
#### Input Field
- **The thermal efficiency is:** \[ \boxed{0} \] \%
The box above is for inputting the calculated thermal efficiency percentage.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F19222922-2f42-4a31-8a19-d5030e65668d%2F645fd035-9374-4bee-ad1e-33cab4f7ecb8%2Fdxjog2h_processed.png&w=3840&q=75)
