The correct match is as follows:

The correct match is as follows:

Note: Pass is a path for crossing a mountain.

The correct match is as follows:

Note: Headquarter of TISCO and BPCL is in Mumbai while BALCO’s Headquarter is in Bhubaneshwar and BEL’s Headquarter is in Bengaluru.

The correct match is as follows:

Note: National Highways Authority of India (NHAI) is the nodal agency responsible for building, upgrading and maintaining most of the national highways network

One carbon credit is accepted as equivalent to 1000 kg of carbon dioxide.

• These credits are used for carbon trading.
• The holder of carbon credit can emit carbon dioxide and other greenhouse gases.
• The issuance of carbon credits aims to reduce the emission of greenhouse gases into the atmosphere.

Note: Proposal of Carbon credit was presented by IPCC and ratification of International carbon credit system is in agreement with the Kyoto Protocol.

The correct answer is two liquids

• An emulsion is a special type of colloid made by combining two liquids that normally don't mix.
•  Examples of emulsions are Egg yolk, butter etc.
•  Even though the liquids that form them may be clear, emulsions appear cloudy or colored because light is scattered by the suspended particles in the mixture.

Note: An emulsion is a type of colloid, but not all colloids are emulsions.

The correct answer is All of the above

All these radioactive substances enters the human body through food chain and causes many physiological disorders.

• Strontium-90 is particularly dangerous for growing children and is believed to contribute to bone cancer and leukemia
• High exposure to Iodine-131 affects the thyroid gland
• Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation.

Xeriscaping reduces or eliminates the need for supplemental water by proper landscaping and gardening.

Note:

Xeriscaping is based on the following principles:

• Planning and Design
• Soil Improvement
• Practical Turf Area
• Efficient Irrigation
• Mulch
• Low Water-Use Plants
• Appropriate Maintenance

The answer is Isenthalpic process

• Joule-Thomson process is a throttling process in which the temperature of a gas or liquid decreases when it is forced through an insulated valve.
• The gas-cooling throttling process is used in refrigeration processes such as air conditioners, heat pumps, and liquefiers.

Note: Hydraulic oil gets warm when throttled and can be used to detect leakages.

Ultrasonic waves are produced by making use of piezoelectric material.

• Ultrasonic waves are used to detect objects and measure distances.
• They have frequency greater than 20 kHz and humans can’t hear it.

Note: Piezoelectricity means electricity resulting from pressure and latent heat.
