In an ideal gas, at any particular time, different particles in the gas have different speeds and hence different kinetic energies. This assumption is reasonable because as the particles collide, we expect their speed to change. Even if initial speed of all the particles was same, the molecular collisions will disrupt this uniformity.Hence statement 1 is incorrect and 2 is correct.

In communication satellite, multiple repeaters are known as Transponders.

Jim Corbett National Park is the 1st National Park of India and is a forested wildlife sanctuary in northern India’s Uttarakhand State. Rich in flora and fauna, it’s known for its Bengal tigers.

Isotopes are variations of an element that have the same charge as the original element, but a different mass, which is caused by either more/less neutrons in the nucleus.

Yes, we know that water is a universal solvent.

Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization.

Water is a polar molecule that has a high level of polarity and attraction to ions and other polar molecules.

Hence, all the above given options are the properties of water.

The speed of all the electromagnetic radiation are always   same   and   equal   to   the numerical value 3 x 10^8m/sec.
