250+ TOP MCQs on Heat Rejection and Cooling and Answers

Automobile Engineering Multiple Choice Questions on “Heat Rejection and Cooling”.

1. Why is radiator provided?
a) To cool the jacket water
b) To pressurize the cooling water
c) To provide additional water flow
d) To cool the external surface of the engine
Answer: a
Clarification: Radiator is provided to cool the jacket water. The heat from the combustion gases is transferred to the various parts of the engine like cylinder head and walls, piston and valves.

2. Why is thermostat used?
a) To control the velocity of water
b) To control the distribution of water to various cylinders
c) To control the water temperature
d) To control the pressure of water
Answer: c
Clarification: Thermostat is used to control the water temperature. Whenever the engine is started from cold, the coolant temperature has to be brought to the desired level so that the warmup time is less.

3. What is the advantage of the liquid cooling system?
a) Dependent only on water supply
b) Power absorbed by the pump is considerable
c) Even cooling
d) Very cheap
Answer: c
Clarification: The advantage of the liquid cooling system is even cooling. In this system, water is used as a coolant and made to circulate through the jackets provided around the cylinder, cylinder head, valve ports and seats.

4. What is the material of the radiator cooling tube?
a) Rubber
b) Plastic
c) Brass
d) Copper
Answer: d
Clarification: Radiator cooling tubes are made of copper. Radiator cores are classified as tubular or cellular. The main disadvantage is repairing any of the damaged tubes.

5. What is a direct system of cooling the air?
a) Cooling water flows by gravity
b) Hot water is continuously cooled and circulated
c) Hot water is simply discharged
d) Water is allowed to evaporate in the cylinder jacket
Answer: c
Clarification: In direct system of cooling air, hot water is simply discharged. In air-cooled system, a current of air is made to flow past the outside of the cylinder barrel.

6. Which pump is used in a forced cooling system?
a) Piston pump
b) Gear pump
c) Vane pump
d) Centrifugal pump
Answer: d
Clarification: Centrifugal pump is used in a forced cooling system. The pump is used to maintain the circulation of the water through the system. The power is transmitted to the pump spindle.

7. What is the purpose of the thermostat in an engine cooling system?
a) To allow the engine to warm-up quickly
b) To prevent the coolant from boiling
c) To pressurize the system
d) To indicate to the driver the coolant temperature
Answer: a
Clarification: The thermostat is used to allow the engine to warm-up quickly. The thermostat unit consists of closed bellows with a volatile liquid.

8. Why does the engine overheating happen?
a) Due to a broken fan belt
b) Due to excess coolant
c) Due to an open thermostat
d) Due to the stuck radiator pressure cap
Answer: a
Clarification: The engine overheating happens due to a broken fan belt. When a fan is broke, it cannot cool the hot water. It should be capable of removing about 30% of the heat from the combustion chamber.

9. What is the purpose of a fan in a liquid cooling system?
a) To disperse engine fumes
b) To pump cold air over the hot water
c) To cool the external surface of the engine
d) To drive airflow when the vehicle speed is low

10. How does the water circulation happen in a thermosyphon cooling system?
a) Due to conduction currents
b) Due to a gear drove water pump
c) Due to change in the density of water
d) Due to a belt-driven water impeller
Answer: a
Clarification: The water circulation happens in a thermosyphon cooling system due to conduction currents. This system is simple and automatic.

250+ TOP MCQs on Wave Optics – Polarisation | Class12 Physics

Physics Multiple Choice Questions on “Wave Optics – Polarisation”.

1. Which type of waves shows the property of polarization?
a) Infrared
b) Longitudinal
c) Transverse
d) Microwave
Answer: c
Clarification: Only transverse waves show the property of polarization. Their vibrations can occur in all directions perpendicular to the direction of travel. The longitudinal, infrared, and microwaves do not show the property of polarization.

2. What will be the angle of refraction in the glass, if the polarization angle for the air-glass interface is 63.8^o?
a) 56.3^o
b) 33.7^o
c) 90^o
d) 0^o
Answer: b
Clarification: As i_p + r_p = 90^o
r_p = 90^o – 63.8^o
r_p = 26.2^o
Therefore, the angle of refraction in the glass is 26.2^o.

3. What is the polarization angle of a medium of refractive index √3?
a) 60^o
b) 120^o
c) 30^o
d) 90^o
Answer: a
Clarification: tan i_p = μ = √3.
i_p = tan^-1(√3)
i_p = 60^o
Therefore, the polarization angle of a medium of refractive index √3 is 60^o.

4. What are sunglasses made of?
a) Colored glasses
b) Tin glass
c) Silica
d) Polaroids
Answer: d
Clarification: Polaroids absorb only that part of the light which produces a dazzling effect in the eye. But colored glasses absorb more light incident on them and so the image appears dim. Therefore, sunglasses are made of Polaroids.

5. Which field vector is used to represent the polarization of an em wave?
a) Potential field vector
b) Magnetic field vector
c) Electric field vector
d) Dipolar field vector
Answer: c
Clarification: An electric field vector is used to represent the polarization of an em wave. It is perpendicular to the plane of propagation of the light wave. Therefore, a vertically polarized electromagnetic wave of wavelength λ has its electric field vector oscillating in the vertical direction.

6. Sound waves can be polarized.
a) True
b) False
Answer: b
Clarification: Unlike transverse waves such as electromagnetic waves, longitudinal waves such as sound waves cannot be polarized. This is because, sound waves vibrate along their direction of propagation, and thus, cannot be polarized.

7. Identify the property which is not mutually perpendicular to the polarized light wave in a plane.
a) Plane of vibration
b) Plane of rotation
c) Plane of polarization
d) The direction of propagation of the light wave
Answer: b
Clarification: Plane of vibration, the plane of polarization, and direction of propagation of the light wave are mutually perpendicular to the polarized light wave in a plane. The other factors are not mutually perpendicular to the polarized light wave in a plane.

8. Which plane is defined as the plane of polarization in a plane-polarized electromagnetic wave?
a) The plane containing the direction of propagation of light
b) The plane containing the direction of reflective wave
c) The plane containing the direction of refractive wave
d) The plane containing the direction of dispersive wave
Answer: a
Clarification: The plane containing the direction of propagation of light and perpendicular to the plane of vibration is called the plane of polarization. It contains no vibrations. Polarized light waves are light waves in which the vibrations occur in a single plane.
