c) Satu mol gas monoatomik pada tekanan 1.5 x 10$ Pa dan isipadu 5.0 x 103 m³ pada 120 °C menjalani proses isovolumetrik sehingga tekanannya ialah 2.8 x 105 Pa. Gas itu kemudian mengalami pengembangan secara isoterma sehingga isipadunya mencapai 20.0 x 103 m?. A mole of monoatomic gas at pressure 1.5 x 10 5 Pa and volume 5.0 x 10 3 m at 120 °C undergoes an isovolumetric process until its pressure is 2.8 x 105 Pa. The gas is then expanded isothermally until its volume reached 20.0 x 10³m². (i) Kira suhu akhir gas dalam unit darjah Celsius. Calculate the final temperature of the gas in Celsius degree unit. (ii) Kira tekanan akhir gas. Calculate the final pressure of the gas. (iii) Kira kerja yang dilakukan terhadap gas semasa pengembangan isoterma. Calculate the work done on the gas during the isothermal expansion.
