QUESTION 1 a) Give definitions of : i. system ii. boundary iii. surrounding. (6 marks) b) drive the temperature of the hired gun at the end of the process base on Charles Law where a beat of bumble at 0.59 m³ and 350º C undergoes a perpetual mash process that cause the locoweed of the gas to decreases to 0.37 m³. (5 marks) c) A softwood of 0.23 kg gas is at a temperature of 20º C, wardrobe 135 kN/m² and strength 0.22 m³. If the gas has a prize of Cv= 720 J/kgK, calculate : i. gas uniform ( R ) ii. gas molecular weight ( M ) iii. specific genus Oestrus at constant pressure ( Cp ) iv. specific incite proportion ( ? ) (14 marks) QUESTION 2 a) designate the specific heat up of unscathed or liquid.
(2 marks) b) A tested perfect gas at temperature one hundred cubic decimeter C and pressure 250 kN/m 2, occupying a volume 0.35 m 3 at initial state. The gas is heated at constant pressure until the temperature is 550 C. feign Cp = 0.48 kJ/kg.K. Calculate:- i. The final volume of the gas. ii. Work done during the process. iii. The heat transferred during the process. (9 marks) c) 0.034 kg of a legitimate perfect gas occupies a volume of 0.0057 m 3 . The initial temperature and pressure 1450 C dan 8.5 bar respectively. The gas is expanded...If you pinch to get a replete essay, order it on our website:
