Q3. All the laws of thermodynamics and haet transfer in thermal engineering .
Ans. 
Thermodynamics and heat transfer are fundamental principles in thermal engineering, governing energy transfer and conversion.
• First law of thermodynamics: Conservation of energy, stating that energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics: Entropy always increases in a closed system, leading to the direction of heat flow.

• Third law of thermodynamics: As temperature appro...read more

Q4. All the mechanical properties in som .
Ans. 
Mechanical properties in materials refer to characteristics related to their behavior under applied forces.
• Mechanical properties include strength, hardness, toughness, ductility, and elasticity.

• Strength is the ability of a material to withstand an applied force without failure.

• Hardness is the resistance of a material to deformation or scratching.

• Toughness is the ability of a material to absorb energy and plastically de...read more

Q5. All the process in RAC .
Ans. 
RAC stands for Refrigeration and Air Conditioning. It involves various processes like compression, condensation, expansion, and evaporation.
• Compression: The refrigerant gas is compressed to increase its temperature and pressure.

• Condensation: The high-pressure gas releases heat and condenses into a liquid.

• Expansion: The liquid refrigerant passes through an expansion valve, reducing its pressure and temperature.

• Evaporati...read more

Q1. Difference between Melting point and boiling point. Regnault's law
Ans. 
Melting point is the temperature at which a solid turns into a liquid, while boiling point is the temperature at which a liquid turns into a gas. Regnault's law states that the vapor pressure of a liquid is directly proportional to its temperature.
• Melting point is the temperature at which a substance changes from solid to liquid state.

• Boiling point is the temperature at which a substance changes from liquid to gas stat...read more

Q2. Define Flash Point
Ans. 
Flash point is the temperature at which a substance gives off enough vapor to ignite in air.
• Flash point is a safety measure for flammable liquids.

• It is determined using a closed cup or open cup method.

• Lower flash point indicates higher flammability.

• Example: Gasoline has a flash point of around -40°C.

Q4. Equilibrium point for engine
Ans. 
Equilibrium point for engine is the point where the engine's power output equals the resistance forces.
• Equilibrium point is where the engine's power output matches the resistance forces acting on it.

• It is important for efficient operation of the engine.

• Example: In a car engine, the equilibrium point is reached when the engine power output matches the resistance from air drag and friction.

• At equilibrium point, the engin
