What is 3.9 cm? Please help me

Chemistry
1 answer:
Butoxors [25]4 years ago
5 0

It is a unit of measurement. It seems like an incomplete question. 3.9cm is 3.9cm. If your asked to convert it to something then it looks like this.

1inch=2.54cm

x inches = 3.9cm

\frac{3.9}{2.54}= 1.5 inches

Hope that helps. For a better answer I would need what the question is asking.

When the temperature of a sample of neon gas increases, what else increases? Distance between the atoms Kinetic energy of the at
Allushta [10]

Answer: 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:

K.E._({avg})=\frac{3RT}{2N_A}

where, K = Average Kinetic energy

R = Gas constant

T = Temperature

N_A = 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.
