Which temperature represents the highest average kinetic energy of the particles in a sample of matter ?

1 answer:

6 0

Average kinetic energy is proportional to absolute temperature. This means that the higher the temperature the higher the kinetic energy.

This equation reflects that: KE avg = [3/2]kT, where k is the Boltzman constant.

So, you just have to checkg which of the given temperatures is the highest one..

Of course to compare you need to have them all in the same unit system.

Use absolute temperatures in Kelvin.

=> 27°C + 273.15 = 300.15 K.

Then, the highest temperature is 27°C and that represents the highest kinetic energy.

Answer is the option c. 27°C

K forms the compound K2O , which is an ionic compound that is brittle. Identify another element, M , that is likely to form a br

meriva

The metal is sodium, Na.

<u>Explanation:</u>

K₂O is an ionic compound in which K is in the oxidation state of +1 and it belongs to group 1.

Group 1 elements also form oxides with the metals with the general formula M₂O and M being Na, K, Li and so on.

Metals Like sodium and Potassium are so brittle in nature and also their oxides.

So the other metal that form metal oxide which is brittle as well as ionic in nature, and so the metal oxide is Na₂O.

So the metal is sodium, Na.
