Suspended colloidal particles in the water can be removed by the process of:
Correct Answer
D. Coagulation
Explanation
Coagulation is the process of causing suspended particles to come together and form larger particles, which can then be easily removed from the water. This is typically achieved by adding a coagulant, such as aluminum sulfate or ferric chloride, to the water. The coagulant neutralizes the charges on the particles, allowing them to come together and form flocs. These flocs can then be removed through processes like sedimentation or filtration. Coagulation is an effective method for removing colloidal particles from water, as it helps to improve the clarity and quality of the water.

A white solid 'N on heating gives off a gas which turns lime water milky. The residue is yellow' when hot but turns white on cooling. The solid A is
Correct Answer
A. Zinc carbonate
Explanation
When the white solid 'N' is heated, it gives off a gas that turns lime water milky. This indicates the presence of carbon dioxide gas, which is produced when carbonates are heated. The residue left behind after heating is yellow when hot, but it turns white upon cooling. This color change suggests that the yellow residue is a hydrated compound, and upon cooling, the water molecules evaporate, leaving behind the white solid. The only compound that fits this description is zinc carbonate, making it the correct answer.

Which of the following is the strongest coagulant?
Correct Answer
B. Aluminum chloride
Explanation
Aluminum chloride is the strongest coagulant among the given options. Coagulants are substances that are used to clump together suspended particles in a liquid, making them easier to remove. Aluminum chloride is commonly used in water treatment processes as it has a high positive charge, which allows it to attract and neutralize negatively charged particles more effectively than the other options. This strong positive charge enables aluminum chloride to form larger and denser flocs, resulting in better coagulation and sedimentation of impurities in water.

17.
The property which is seen in light wave but 'not in sound wave is:
Correct Answer
C. Polarisation
Explanation
Polarisation is the property that is seen in light waves but not in sound waves. Polarisation refers to the orientation of the electric field vector in a wave. Light waves can be polarised, meaning that the electric field oscillates in a specific direction, while sound waves cannot be polarised. Sound waves are longitudinal waves, where the particles of the medium vibrate parallel to the direction of wave propagation, and there is no specific orientation of the vibration. Therefore, polarisation is a property unique to light waves and not observed in sound waves.
18.
Iron and manganese are removed in water by the process of:
Correct Answer
D. Aeration
Explanation
Aeration is the process of introducing air into water, which helps to remove dissolved iron and manganese. When water containing these metals is exposed to air, the metals oxidize and form solid particles, which can then be filtered out. This process is commonly used in water treatment plants to improve the quality of drinking water by removing these undesirable substances. Chlorination is the process of adding chlorine to water to disinfect it, filtration is the process of passing water through a filter to remove impurities, and lime-soda treatment is a process that uses lime and soda ash to remove hardness-causing minerals from water.
19.
CPU performance is often measured in:
Correct Answer
B. MIPS
Explanation

Chiropterophily means:
Correct Answer
C. Pollination by bat
Explanation
Chiropterophily refers to the process of pollination by bats. Bats play a crucial role in the pollination of certain plants, particularly those that bloom at night and have strong scents or produce nectar. Bats are attracted to these plants and while feeding on nectar, they inadvertently transfer pollen from the male reproductive parts of one flower to the female reproductive parts of another flower, facilitating pollination. This unique form of pollination is essential for the reproduction and survival of many plant species.
34.
Which one of following is called the primary pace maker of the heart?
Correct Answer
D. S. A. Node
Explanation
The S. A. Node, also known as the sinoatrial node, is called the primary pacemaker of the heart. It is responsible for initiating the electrical signals that regulate the heart's rhythm and coordinate the contractions of the atria. The S. A. Node is located in the right atrium near the opening of the superior vena cava. It generates electrical impulses that travel through the atria, causing them to contract and pump blood into the ventricles. From there, the impulses are transmitted to the A. V. Node, which further relays them to the ventricles, causing them to contract and pump blood out of the heart.
35.
When granite rocks get metamorphosed, they change into
Correct Answer
