Chemical Engineering :: Chemical Engineering Thermodynamics
- Chemical potential is a/an
- For an ideal gas, the chemical potential is given by
- Boiling of liquid is accompanied with increase in the
- Law of corresponding states says that
- Free energy, fugacity and activity co-efficient are all affected by change in the temperature. The fugacity co-efficient of a gas at constant pressure ____with the increase of reduced temperature.
- Any substance above its critical temperature exists as
- First law of thermodynamics is mathematically stated as
- A cyclic engine exchanges heat with two reservoirs maintained at 100 and 300°C respectively. The maximum work (in J) that can be obtained from 1000 J of heat extracted from the hot reservoir is
- Cv for an ideal gas

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) |
