- Air expands from initial condition of p1, v1 to final condition of 1/2 p1, 2v1. Choose the correct statement
- A gas expands from initial condition of (p1, v1, T1) to final condition (p2, v1, T2), then according to Charle's law:
- A mixture of gases expands from 0.03 m³ to 0.06 m³ at a constant pressure of 1 Mpa & absorbs 84 kJ of heat during the process. The change in internal energy of the mixture is
- When considering a finite energy source, its working fluid expands,
- A series of operations, which take place in a certain order & restore the initial condition is known as
- A process which can be stopped at any stage & reversed so that the system & the surroundings are exactly restored to their initial states is known as
- 1.6 Kg of air is expanded at constant pressure from 100°C to 0°C resulting in entropy change of - 2.0 J/K 3.2 Kg of air is cooled at constant volume from 100°C to 0°C with a change in entropy of -3.0 J/K. The ratio Cp/ Cv is
- Cooling and dehumidification of air is done in summer air conditioning.
- When humidity ratio of air air is said to be dehumidified.
- A sequence of operations which a gas undergoes in such a way that final state is same as original state, mahe a
