Q2. 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 state.

  • Regnault's law states that the vapor pressure of a liqui...read more

Q4. Combination of stell ,iron carbon digram

Ans.

The iron-carbon diagram shows the relationship between carbon content and the properties of steel and iron.

  • The diagram plots the percentage of carbon in the alloy against its temperature.

  • It helps in understanding the behavior of steel and iron during heating and cooling.

  • The diagram shows the different phases of steel and iron, such as ferrite, austenite, and pearlite.

  • The diagram is used to determine the heat treatment required to achieve desired properties in steel and iron.

Q5. What is least count

Ans.

Least count is the smallest measurement that can be made using the measuring instrument.

  • Least count is determined by the smallest division on the scale of the measuring instrument.

  • It helps in determining the precision of the instrument.

  • For example, if a ruler has smallest division of 1 mm, its least count is 1 mm.

  • In vernier calipers, the least count is calculated as main scale division - vernier scale division.

Q6. 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 engine is neither accelerating nor decelerating.

Q7. 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.
