Important questions about Chemical Engineering Thermodynamics. Chemical Engineering Thermodynamics MCQ questions with answers. Chemical Engineering Thermodynamics exam questions and answers for students and interviews.
A : , two different gases behave similarly, if their reduced properties ( i . e . P, V and T) are same.
B : the surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature.
C : no gas can be liquified above the critical temperature, howsoever high the pressure may be.
D : the molar heat of energy of gas at constant volume should be nearly constant (about 3 calories).
A : Compression ratio of an Otto engine is comparatively higher than a diesel engine.
B : Efficiency of an Otto engine is higher than that of a diesel engine for the same compression ratio.
C : Otto engine efficiency decreases with the rise in compression ratio, due to decrease in work produced per quantity of heat.
D : Diesel engine normally operates at lower compression ratio than an Otto engine for an equal output of work.
