Question
1. The following data were observed when a gas was compressed. Calculate the work needed to compress 1 kg of the gas from 15 bar to 90 bar. | P (bar) | 15 | 30 | 45 | 60 | 75 | 90 | |---------|-----|-----|-----|------|------|------| | V (m³/kg) | 58 | 29 | 19.3 | 14.45 | 11.55 | 9.62 | **Explanation:** The table shows the relationship between pressure (P) in bars and specific volume (V) in cubic meters per kilogram as the gas is compressed. The pressure increases while the specific volume decreases, indicating compression of the gas. The task is to calculate the work required for this compression process.
