Which of the following statements is true?
Kazeer [188]
Only one: the nucleus of an atom is made up of protons and neutrons.
Why others are false:
Boiling point of a substance is not dependent on the volume because it’s a intensive property.
During sublimation, a solid changes directly into gas.
Electrons orbit the nucleus of an atom in circular orbits (kinda unsure of this one.)

A flask contains a mixture of neon Ne, krypton Kr, and radon Rn gases. (Hint: The molar mass of the Ne is 20.180 g/mol, of the K
Nataly_w [17]

Answer:

Kinetic energies of all the gases are same.

Explanation:

The average kinetic energy of molecules of a gas is given by the formula:

K.E = (3/2)KT

where,

K.E = Average Kinetic Energy of the molecule

K = Boltzman's Constant = 1.38 x 10^-23 J/K

T = Absolute temperature of gas

Since, all the gases are in a mixture, and the temperature of the gases must be same and equal to the temperature of mixture.

Therefore, all the terms in the formula are constant and the <u>Average Kinetic Eenergies of all the gases in the mixture (namely, Neon Ne, Krypton Kr, Radon Rn), equal.</u>
