Laws governing energy and its transformations in physical systems.
First law: Energy cannot be created or destroyed, only transferred or converted.
Second law: Entropy of a closed system always increases over time.
Third law: Absolute zero cannot be reached.
Applications in engineering, physics, and chemistry.
Examples: heat engines, refrigeration, combustion, chemical reactions.
- Q2. Principle of steam ejectors.
- Ans.
Steam ejectors are devices that use steam to create a vacuum by entraining and compressing gases or vapors.
Steam ejectors work by using a high-pressure steam jet to create a low-pressure zone, which draws in gases or vapors from the surrounding area.
The entrained gases or vapors are then compressed and discharged through a diffuser, which increases their velocity and reduces their pressure.
Steam ejectors are commonly u...
- Q3. Working of heat pump.
- Ans.
Heat pump is a device that transfers heat from a lower temperature to a higher temperature.
Heat pump works on the principle of refrigeration cycle.
It consists of four main components: evaporator, compressor, condenser, and expansion valve.
The refrigerant absorbs heat from the low-temperature source (air, water, or ground) in the evaporator and gets converted into a gas.
The compressor then compresses the gas, which incr...
