S1.Ans. (b)
Sol. Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature it is colourless, odorless, non – inflammable gas, with a slightly sweet taste.

S2.Ans. (b)
Sol. SQL (Structured Query Language) is a specialpurpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

S3.Ans. (a)
Sol. Raw mangoes shrivel when pickled in brine due to osmosis i.e. flow of water from higher concentration to lower concentration through a semi-permeable membrane.

S4.Ans. (a)
Sol. Ice under black wrap will melt easily because dark colour (black) absorbs the most of light energy falling on it.

S5.Ans. (b)
Sol. The hollow bricks provide thermal insulations; the air in hollow bricks, does not allow outside heat or cold in the house to go out or come in the house. So, it keeps house cool in summer and warm in winter.

S6.Ans. (c)
Sol. When a body is immersed in a fluid, the fluid exerts an upward force on it, called buoyant force. and buoyant force ∝ density of fluid. As the density of sea water is higher than that of the fresh water. So extra buoyant force and ship will rise a little higher.

S7.Ans. (a)
Sol. As the cat falls from a height, it bends the legs to absorb the impact of falling and immediately adjust itself.

S8.Ans. (d)
Sol. When CO is not ventilated it binds to haemoglobin, which is the principal oxygen-carrying compound in blood; this produces a compound known as carboxyhaemoglobin. Carbon monoxide toxicity arises from the formation of carboxyhaemoglobin, which decreases the oxygen-carrying capacity of the blood and inhibits the transport, delivery, and utilization of oxygen by the body.

S9.Ans. (c)
Sol. Fire fly gives us cold light due to chemiluminescence i.e. light produced by chemical reaction.

S10.Ans. (a)
Sol. X-rays are types of electromagnetic radiation probably most well-known for their ability to see through a person’s skin and reveal images of the bones beneath it. X-rays carries the maximum energy per photon.
