Items

Spherical shape of small falling raindrops
Operation of hydraulic brakes in automobiles
Apparent twinkling of stars in the night sky
Cooling effect of water stored in an earthen pot (matka)

Matches

Show answer & explanation

Answer

The correct matching pairs are: Spherical shape of falling raindrops matches with Minimization of surface area driven by Surface Tension; Operation of hydraulic brakes matches with Equal transmission of fluid pressure according to Pascal's Law; Apparent twinkling of stars matches with Light ray deviation caused by Atmospheric Refraction; and Cooling effect of water in an earthen pot matches with Latent heat absorption during Evaporative Cooling.
Each observation directly matches its underlying physical law: surface tension minimizes surface area for raindrops; Pascal's Law governs hydraulic pressure transmission; atmospheric refraction causes stellar twinkling; and latent heat absorption during evaporation cools water in porous vessels.

Step-by-Step Solution

1
Identify the cause behind the spherical geometry of small falling liquid drops.
Cohesive intermolecular forces at the liquid surface create surface tension, minimizing the surface area into a sphere.
A sphere possesses the smallest surface-area-to-volume ratio among all geometric shapes.
2
Analyze the operational principle of hydraulic braking systems.
Force applied to the brake pedal creates pressure in the brake fluid, which is transmitted equally across the system to actuate pistons at the wheels.
According to Pascal's Law, static fluid pressure is transmitted undiminished throughout an enclosed fluid system.
3
Determine the cause of stellar scintillation (twinkling).
Starlight passes through turbulent atmospheric layers with fluctuating temperatures and optical densities, causing constant shifting of the ray paths.
Atmospheric refraction alters the apparent brightness and position of point-source light continuously.
4
Explain the thermodynamic cooling of water in porous earthen vessels.
Water seeping out through microscopic pores evaporates from the outer surface, extracting thermal energy from the pot.
Evaporation requires energy equivalent to the latent heat of vaporization, lowering the temperature of the remaining system.

Statutory Liquidity Ratio (SLR)

Matches

Show answer & explanation

Answer

Marginal Standing Facility (MSF) pairs with the emergency overnight borrowing window against securities; Standing Deposit Facility (SDF) pairs with the uncollateralized liquidity absorption mechanism; Cash Reserve Ratio (CRR) pairs with mandatory cash reserves parked with the RBI without interest; Statutory Liquidity Ratio (SLR) pairs with mandatory liquid assets (gold, G-Secs) maintained by banks themselves.
Each monetary policy tool matches its operational feature: MSF is an emergency borrowing window above repo requiring collateral; SDF acts as an uncollateralized liquidity absorption floor; CRR represents non-interest-bearing cash parked with RBI; and SLR denotes liquid assets (primarily G-Secs and gold) held by commercial banks.

Step-by-Step Solution

1
Identify the primary collateral requirements and interest earning aspects of quantitative tools.
Differentiate between collateralized/uncollateralized instruments and cash vs asset reserve requirements.
MSF requires collateral (G-Secs) at a higher rate, whereas SDF absorbs liquidity without collateral.
2
Analyze CRR versus SLR reserve requirements.
CRR is maintained exclusively in cash balances with the RBI, whereas SLR is maintained by banks in liquid assets like G-Secs and gold.
CRR controls bank lending capacity directly via central bank reserves, while SLR ensures solvency and creates domestic market demand for government bonds.
3
Match each tool in Column I to its accurate definition in Column II.
MSF -> Emergency overnight borrowing; SDF -> Uncollateralized liquidity floor; CRR -> Unremunerated cash reserves with RBI; SLR -> Liquid asset holdings (G-Secs/gold).

Question 379Question

Match the chemical compounds and industrial materials in List-I with their corresponding primary application or functional property in List-II:

Click a left item, then click its matching right item

Items

Calcium Carbide (CaC2CaC_2)
Sodium Benzoate (C6H5COONaC_6H_5COONa)
Superphosphate of Lime
Bakelite Polymer

Matches

Show answer & explanation

Answer

Calcium Carbide matches with artificial fruit ripening via moisture-triggered acetylene generation; Sodium Benzoate matches with food preservation in acidic environments; Superphosphate of Lime matches with water-soluble phosphatic fertilizer production via sulfuric acid treatment of rock phosphate; and Bakelite Polymer matches with thermosetting resin used for electrical insulation and cookware handles.
Each compound is accurately matched with its primary chemical role: Calcium Carbide releases acetylene for fruit ripening; Sodium Benzoate serves as an acidic food preservative; Superphosphate of Lime provides water-soluble phosphorus for crops; and Bakelite provides heat-resistant electrical insulation as a thermosetting plastic.

Step-by-Step Solution

1
Analyze the chemical reactivity and practical use of Calcium Carbide (CaC2CaC_2).
Calcium carbide undergoes hydrolysis upon contact with water to produce acetylene gas (C2H2C_2H_2) according to the reaction: CaC2+2H2OCa(OH)2+C2H2CaC_2 + 2H_2O \rightarrow Ca(OH)_2 + C_2H_2.
Acetylene gas acts as an analogue to ethylene, inducing artificial ripening in fruits like mangoes and bananas.
2
Determine the mode of action of Sodium Benzoate (C6H5COONaC_6H_5COONa).
In acidic media (such as fruit juices and carbonated beverages), sodium benzoate converts into undissociated benzoic acid.
The undissociated acid readily diffuses across microbial cell walls to disrupt glucose fermentation, acting as an effective preservative.
3
Evaluate the industrial synthesis of Superphosphate of Lime fertilizer.
Insoluble calcium phosphate mineral in rock phosphate is treated with sulfuric acid: Ca3(PO4)2+2H2SO4Ca(H2PO4)2+2CaSO4Ca_3(PO_4)_2 + 2H_2SO_4 \rightarrow Ca(H_2PO_4)_2 + 2CaSO_4.
The resulting monocalcium phosphate is water-soluble, allowing plant roots to readily absorb bioavailable phosphate nutrients.
4
Identify the polymer structure and physical properties of Bakelite.
Bakelite is produced by step-growth condensation polymerization of phenol with formaldehyde in the presence of an acid or base catalyst.
Extensive 3D covalent cross-linking makes Bakelite a thermosetting plastic that does not melt upon heating, making it suitable for electrical switches and appliance handles.
