Question 3 of 5
3. Question
1 pointsWith reference to Piezoelectric materials, consider the following statements:
- Piezoelectric materials can generate an electric charge when subjected to mechanical pressure.
- Piezoelectric materials contain only atoms arranged in a random pattern.
- Stove lighters work on the principle of Piezoelectric effect.
Which of the statements given above are correct?
Correct
Answer: C
Explanation:
- Statement 1 is correct: A piezoelectric material is a material where charge accumulates in response to applied mechanical stress. They can effectively create a surplus and a deficiency of electrons when they are under some pressure. As it happens, they can also easily remove this surplus when the applied pressure is removed. The reason these materials can do this is because the atoms in a piezoelectric material are arranged in a slightly funny periodic pattern.
- Statement 2 is not correct: They also usually have two types of atoms that have two different charges. One has a surplus of electrons and the other has a deficiency, i.e. they are negative and positive ions. Now, under no extra pressure, these atoms are arranged in an alternating pattern and in such a way that there is no surplus of electrons at one end compared to another. When some pressure is applied, the picture changes. The structure of these materials is such that, under pressure, the positive ions move in one direction and the negative ones move in the other direction. This creates a surplus at one end of the material and a deficiency at the other end. Essentially, the material has become a battery!
Statement 3 is correct: The stove lighter works on the principle of piezoelectric effect. In simpler terms, pressing a button on a piezoelectric lighter causes a small hammer to strike a piezoelectric crystal (mainly Quartz, a type of ceramic), producing a high-voltage spark that ignites the fuel.

Question 4 of 5
4. Question
1 pointsConsider the following:
- Reduced absorption of carbon by plants
- Increased transpiration in plants
- Stunted growth of plants
How many of the above are most likely impacts of coal dust settling on plants?
Correct
Answer: B
Explanation:
- Coal mine dust is a complex and heterogeneous mixture containing more than 50 different elements and their oxides. The mineral content varies with the particle size of the dust and with the coal seam.
- Point 1 is correct: Apart from being important for photosynthesis in plants, carbon absorption lowers the amount of carbon dioxide in the air. But when dust clogs the stomata, the plant absorbs less carbon and leaves more carbon dioxide in the atmosphere. This could worsen global warming over time.
- Point 2 is not correct: Another effect of clogged stomata is that plants become less able to exude water vapour in a process called transpiration. Plants that transpire well are able to maintain their temperature better; those that don’t become warmer.
Point 3 is correct: “When leaves are too hot, they struggle to photosynthesise efficiently,” Gorai explained. “Over time, this can lead to stunted growth or even the death of plants.” This then leads to long-term damage to local ecosystems.

Question 5 of 5
5. Question
1 pointsConsider the following statements:
- The first oil well was drilled in Maharashtra in 1867.
- Gross Value Addition (GVA) of manufacture of Coke and Refined Petroleum Products has increased ten times in the last ten years.
- India is the third-largest exporter of refined petroleum products.
How many of the above statements are correct?
Correct
Answer: D
Explanation:
- Statement 1 is not correct: The roots of India’s petroleum industry trace back to 1867 when the first oil well was drilled in Digboi, Assam. This discovery marked the inception of the country’s exploration and production activities. The establishment of the Indian Oil Corporation in 1959 heralded a structured approach to refining and distribution. Over the decades, the sector witnessed significant expansion, from small-scale refineries to a robust network capable of meeting domestic and export demands.
- Statement 2 is not correct: As per the information provided by the Ministry of Statistics and Programme Implementation, Gross Value Addition (GVA) of manufacture of Coke and Refined Petroleum Products has increased from Rs.1.56 lakh Crore in 2012-13 to Rs. 2.12 lakh Crore in 2022-23 (as per first revised estimates) which has also contributed in increase of All India GDP from Rs.99.44 lakh Crore to Rs. 269.49 lakh Crore in the corresponding period, at current prices. It has not increased 10 times.
Statement 3 is not correct: India ranks among the top five refining nations globally, thanks to its robust infrastructure and strategic geographic location. The country is the seventh-largest exporter of refined petroleum products. Facilities like the Jamnagar refinery, one of the world’s largest, underscore India’s dominance in the refining sector. This global standing enhances India’s energy security and positions it as a key player in international energy markets. International Energy Agency (IEA) in February 2024 assessed that India will become the largest source of global oil demand growth between now and 2030. India is the second-largest economy in biofuel blending, following Brazil.
