In order to make efficient solar cooker, the cover of the cooker box should be made of:
-
Transparent plastic sheet
-
Shining aluminium sheet
-
Butter paper sheet
-
Transparent glass sheet
Correct Answer
A. Transparent glass sheetExplanation
The cover of the solar cooker should be made of a transparent material in order to allow sunlight to pass through and heat up the cooker. Transparent glass sheet is the best option as it is durable, allows maximum sunlight to enter, and provides insulation to retain heat inside the cooker. Transparent plastic sheet may not be as durable or insulating, while shining aluminium sheet would reflect sunlight instead of allowing it to pass through. Butter paper sheet may not be transparent enough to allow sufficient sunlight to enter the cooker.Rate this question:

The rise of sea-water during high tide is caused by the gravitational pull of the:
-
Sun
-
Earth
-
Moon
-
Mars
Correct Answer
A. MoonExplanation
The rise of sea-water during high tide is caused by the gravitational pull of the Moon. The Moon's gravitational force attracts the water on Earth's surface, causing it to bulge and create a high tide. This gravitational pull is stronger on the side of the Earth facing the Moon, creating a high tide, and weaker on the opposite side, creating a low tide. The Sun also has an effect on tides, but its gravitational pull is less significant compared to the Moon's.Rate this question:

There are four fuels which all contain only carbon and hydrogen. The fuel having highest calorific value will be one which has:
-
More of carbon but less of hydrogen
-
Less of carbon but more of hydrogen
-
Equal proportions of carbon and hydrogen
-
Less of carbon as well as less of hydrogen
Correct Answer
A. Less of carbon but more of hydrogenExplanation
The fuel with the highest calorific value will have less carbon but more hydrogen. This is because hydrogen has a higher energy content per unit mass compared to carbon. So, a fuel with more hydrogen will release more energy when burned, resulting in a higher calorific value.Rate this question:

The radiation in the sunlight that gives us the feeling of hotness is:
-
Visible radiation
-
Infra-red
-
Red
-
Ultra-violet
Correct Answer
A. Infra-redExplanation
The radiation in sunlight that gives us the feeling of hotness is infra-red. Infra-red radiation has longer wavelengths than visible light, and it is responsible for the heat that we feel from the sun. This type of radiation is not visible to the human eye, but it can be detected as heat. Ultra-violet radiation, on the other hand, is responsible for sunburn and is not associated with the feeling of hotness.Rate this question:

A good fuel is one that possesses:
-
High calorific value and low ignition temperature
-
Low calorific value and low ignition temperature
-
High calorific value and moderate ignition temperature
-
Low calorific value and moderate ignition temperature
Correct Answer
A. High calorific value and moderate ignition temperatureExplanation
A good fuel should have a high calorific value, which means it can produce a large amount of heat energy when burned. This makes it more efficient and cost-effective. Additionally, a fuel with a moderate ignition temperature is desirable as it ensures that the fuel can be easily ignited without requiring excessive heat or energy. This makes it safer and easier to use. Therefore, a fuel with high calorific value and moderate ignition temperature is considered to be a good fuel.Rate this question:

If solar constant is 1.4 kW/m2, then the solar energy received by 1 m2 area in one hour is:
-
5040 J
-
54.0 kJ
-
5040 kJ
-
504.0 J
Correct Answer
A. 5040 kJExplanation
The solar constant represents the amount of solar energy that reaches the Earth's atmosphere per unit area. It is given as 1.4 kW/m2. To calculate the solar energy received by 1 m2 area in one hour, we need to convert the solar constant from kW to J and multiply it by the time in seconds. Since 1 kW = 1000 J/s, the solar constant is equal to 1.4 * 1000 J/s = 1400 J/s. Multiplying this by 3600 seconds (1 hour) gives us 5040 kJ, which is the correct answer.Rate this question:

Coke is more valuable when used:
-
As a fuel for industrial boilers
-
As an oxidizing agent
-
As a reducing agent
-
As a fuel in domestic ovens
Correct Answer
A. As a reducing agentExplanation
Coke is more valuable as a reducing agent because it has the ability to remove oxygen from a substance during a chemical reaction. This property makes it useful in various industrial processes, such as the production of metals from their ores. By acting as a reducing agent, coke helps to extract metals by reducing their oxides to the pure metal form. This makes coke an important component in industries that rely on the reduction of substances.Rate this question:

One atomic mass unit (u) is equivalent to an energy of:
-
93.1 MeV
-
9.31 MeV
-
1 MeV
-
931 MeV
Correct Answer
A. 931 MeVExplanation
One atomic mass unit (u) is equivalent to an energy of 931 MeV. This is because the conversion factor between mass and energy is given by Einstein's famous equation, E=mc^2, where E is energy, m is mass, and c is the speed of light. In this case, the mass is 1 atomic mass unit (u), and when multiplied by the square of the speed of light (c^2), it gives an energy of 931 MeV.Rate this question:

The diagram shows a simple calorimeter system for measuring the heat given out by a liquid fuel burner. The experiment data for four fuels A, B, C, and D are given below. 100 ml (100g) of water was used in the calorimeter to 'collect' the heat given out. The mass of fuel burned and the temperature rise of the water is given. From the data which fuel is the LEAST efficient in terms of energy released per unit mass?
-
Mass of fuel = 0.80g, temperature rise 12oC
-
Mass of fuel = 1.20 g, temperature rise 24oC
-
Mass of fuel = 0.50 g, temperature rise 9oC
-
Mass of fuel = 1.75g, temperature rise 28oC
Correct Answer
A. Mass of fuel = 0.80g, temperature rise 12oCExplanation
The efficiency of a fuel can be determined by calculating the energy released per unit mass. In this case, the energy released is proportional to the temperature rise of the water. The fuel that has the lowest temperature rise for a given mass of fuel burned is the least efficient in terms of energy released per unit mass. Therefore, fuel A, which has a temperature rise of 12oC for a mass of 0.80g, is the least efficient fuel.Rate this question:
