When the temperature of a sample of neon gas increases, what else increases? distance between the atoms kinetic energy of the atoms nuclear energy of the atoms size of the atoms

Kinetic Energy of the atoms also increases.

Explanation: We are given that the temperature of the gas increases.

Relation between kinetic energy and temperature follows:

where, K = Average Kinetic energy

R = Gas constant

T = Temperature

= Avogadro's number

As seen from the relation above, the Kinetic energy of the gas is directly proportional to the temperature, hence as the temperature increases, kinetic energy of the atom also increases.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

a electronegativity decreases beacuse the size of nucleus is bigger.
